Description

Technical Field

[0001] This invention relates to the field of hydrogenated cyclic olefin polymer technology, specifically to a high-performance hydrogenated cyclic olefin polymer, its synthesis method, and its applications. Background Technology

[0002] Ring-opening metathesis polymers (ROMPs) and their hydrogenated polymers have gained wide application due to their excellent light transmittance, water resistance, and processing performance, especially in medical packaging, medical devices, optical lenses, light-transmitting components, and optical films.

[0003] The typical glass transition temperature of hydrogenated cycloolefin polymers is between 100°C and 160°C. In its article "Industrialization and application development of cyclo-olefin polymer" (Journal of Molecular Catalysis A: Chemical 213(2004)81–87), the Japanese company Eion Corporation systematically summarized the properties of various hydrogenated cycloolefin polymers produced by the company. The polymer with the highest glass transition temperature was a hydrogenated polymer using pure tetracyclododecene as a monomer, at 162°C. Yang Jixing's doctoral dissertation, "Novel Polymer Materials Based on ROMP: Design, Synthesis and Performance Study," also synthesized polymers using sterically hindered cycloolefin monomers, obtaining hydrogenated cycloolefin polymers with glass transition temperatures of 223.6°C and 207°C.

[0004] From the perspective of existing technology, if it is necessary to increase the glass transition temperature of hydrogenated cyclic olefin polymers in industrial production, new monomers must be produced, which is not conducive to factories flexibly adjusting product grades to meet market demands. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a high-performance hydrogenated cyclic olefin polymer. By using low-molecular-weight cyclic olefins to synthesize hydrogenated cyclic olefin polymers with high operating temperatures, adding an extra feed stage to the original production line can increase the polymer's glass transition temperature and strength without affecting its amorphous properties. This is highly beneficial for flexibly adjusting products to meet market demands in industrial production.

[0006] This invention provides a method for synthesizing high-performance hydrogenated cyclic olefin polymers, comprising at least the following steps:

[0007] S1. Cycloolefin monomers undergo ring-opening metathesis polymerization, and the reaction is quenched to obtain a ring-opening metathesis polymer solution.

[0008] S2. Under the back pressure of an inert gas, a dicyclopentadiene solution is added dropwise to the ring-opening metathesis polymer solution to carry out a cycloaddition reaction (DA reaction) to obtain the cycloaddition polymer.

[0009] S3. Cycloaddition polymers undergo olefin hydrogenation to obtain hydrogenated cycloolefin polymers.

[0010] As a preferred technical solution, step S1 specifically involves: subjecting a cyclic olefin monomer to a ring-opening metathesis polymerization reaction in the presence of solvent 1 and catalyst 1, and quenching the reaction to obtain a ring-opening metathesis polymer. Preferably, the ring-opening metathesis polymerization reaction is carried out at a temperature of 40-80℃ for 1-3 hours, and more preferably at a temperature of 50-60℃ for 2 hours.

[0011] As a preferred technical solution, the cyclic olefin monomer has ≤14 carbon atoms, and is preferably at least one of different configurations of norbornene, ethylidene norbornene, dicyclopentadiene, cyclopentene, cyclopentadiene, cyclobutene, cyclohexene, tricyclodecene, tricycloundecene, tetracyclododecene, methyl norbornene, methylcyclopentene, methylcyclopentadiene, methylcyclobutene, methylcyclohexene, methyl tricyclodecene, methyl tricycloundecene, and methyl tetracyclododecene. Preferably, the cyclic olefin monomer is at least two of the following: tricyclodecene (CAS: 19398-83-5); tetracyclododecene (CAS: 21635-90-5); methylnorbornene (CAS: 822-96-8); and 2-methyl-tetracyclododecene (CAS: 21681-47-0), preferably a combination of tetracyclododecene and any one of tricyclodecene, methylnorbornene, and 2-methyl-tetracyclododecene, wherein the mass ratio of tetracyclododecene and any one of tricyclodecene, methylnorbornene, and 2-methyl-tetracyclododecene is (5-6):(4-5).

[0012] As a preferred technical solution, the solvent 1 is selected from at least one of toluene, trimethylbenzene, chlorobenzene, dichlorobenzene, cyclohexane, methylcyclohexane, dichloromethane, and carbon tetrachloride, preferably cyclohexane.

[0013] As a preferred technical solution, the total weight of the cyclic olefin monomers is 20-30% of the solvent weight, preferably 25%.

[0014] As a preferred technical solution, the catalyst 1 is a Ziegler-Natta type catalyst without Ru catalyst; the Ziegler-Natta type catalyst includes a main catalyst and a co-catalyst, the amount of the main catalyst added is 0.02-0.03% of the total weight of the cyclic olefin monomers, preferably 0.025%; the amount of the co-catalyst added is 4-6% of the total weight of the cyclic olefin monomers, preferably 5%.

[0015] The main catalyst is a metal chloride, preferably a chloride of at least one metal selected from titanium, molybdenum, and tungsten, and more preferably tungsten chloride; the co-catalyst is a Lewis acid, preferably at least one selected from triethylaluminum, triisobutylaluminum, diethylaluminum chloride, diisobutylaluminum chloride, ethylsilsesquichloride, dichloroethylaluminum, dichloroisobutylaluminum, n-butyllithium, and tert-butyllithium, and more preferably triethylaluminum.

[0016] This invention uses low molecular weight cyclic olefin monomers as raw materials, optimizing the cyclic olefin monomers to a combination of tetracyclododecene and tricyclodecene, methylnorbornene, or 2-methyl-tetracyclododecene in a mass ratio of (5-6):(4-5). This ensures the rigidity and transparency of the hydrogenated cyclic olefin polymer product obtained by subsequent addition reaction with dicyclopentadiene followed by olefin hydrogenation. Furthermore, a Ziegler-Natta catalyst without Ru is used to perform a ring-opening metathesis polymerization reaction at 40-80℃ for 1-3 hours, effectively catalyzing the ring-opening metathesis polymerization of tetracyclododecene and tricyclodecene, methylnorbornene, or 2-methyl-tetracyclododecene, thereby reducing production costs.

[0017] As a preferred technical solution, the mass concentration of dicyclopentadiene in the dicyclopentadiene solution is 1%-50%; the solvent in the dicyclopentadiene solution is the same as the solvent in step S1, preferably cyclohexane.

[0018] As a preferred technical solution, the cycloaddition reaction is carried out at a temperature of 180℃-220℃ and for a reaction time of 0.5-10h.

[0019] As a preferred technical solution, the ratio of the total weight of the cyclic olefin monomers to the weight of dicyclopentadiene in the dicyclopentadiene solution is 100:(0.01-50), preferably 100:(0.01-5).

[0020] Furthermore, during their research, the inventors discovered that by subjecting low molecular weight cyclic olefin monomers to ring-opening metathesis polymerization, followed by quenching the reaction to obtain a ring-opening metathesis polymer solution, and then reacting it with dicyclopentadiene, particularly by controlling the weight ratio of the total weight of the cyclic olefin monomers to the weight of dicyclopentadiene in the dicyclopentadiene solution to 100:(0.01-50), and especially when the weight ratio is 100:(0.01-5), the glass transition temperature and elastic modulus of the hydrogenated cyclic olefin polymer product are further improved while avoiding a significant decrease in light transmittance. The inventors analyzed that the reason might be that, at this mass ratio, dicyclopentadiene undergoes a DA reaction with some of the double bonds on the ring-opening metasomatic polymer to form a norbornene structure (one DA reaction) or a tetracyclododecene structure (two DA reactions). At this time, the product structure effectively improves the elastic modulus and glass transition temperature due to steric hindrance and difficulty in structural torsion. However, if too much dicyclopentadiene is added, on the one hand, the synthesis becomes difficult, and gel is gradually formed during the reaction, leading to a decrease in the product's light transmittance. On the other hand, the product is too brittle and cannot meet the requirements of practical applications.

[0021] As a preferred technical solution, step S3 specifically involves: subjecting the cycloaddition reaction polymer to an olefin hydrogenation reaction in the presence of solvent 2 and catalyst 2 to obtain a hydrogenated cycloolefin polymer.

[0022] Preferably, the olefin hydrogenation reaction is carried out at a temperature of 80-210°C, a hydrogen pressure of 5-10 MPa, and a time of 5-8 h, with a more preferred temperature of 190°C, a hydrogen pressure of 7 MPa, and a time of 6 h.

[0023] As a preferred technical solution, the solvent 2 is the same as the solvent 1, and the amount of solvent 1 added is 20-30% of the total weight of the cycloaddition reaction polymer, preferably 25%.

[0024] As a preferred technical solution, the catalyst 2 is a homogeneous or heterogeneous hydrogenation catalyst or catalytic system, wherein the heterogeneous catalyst is a Pd, Ni, Ru supported or unsupported metal powder catalyst; the homogeneous catalyst is ruthenium acetylacetone or a mixture of nickel acetylacetone and triethylaluminum, preferably a Ni catalyst.

[0025] As a preferred technical solution, the amount of catalyst 2 added is 0.5-2% of the total weight of the cycloaddition reaction polymer, preferably 1%.

[0026] Another aspect of the present invention provides a high-performance hydrogenated cyclic olefin polymer, wherein the high-performance hydrogenated cyclic olefin polymer has a glass transition temperature of 130°C-240°C, or has no glass transition temperature but only a melting point of 240°C-280°C.

[0027] The third aspect of this invention provides an application of a high-performance hydrogenated cyclic olefin polymer in the fields of optical devices, optical films, medical packaging materials, and dielectric materials.

[0028] Beneficial effects

[0029] 1. This invention provides a high-performance hydrogenated cyclic olefin polymer. By using low molecular weight cyclic olefins to synthesize hydrogenated cyclic olefin polymers with high operating temperatures, adding an extra feed section to the original production line can increase the glass transition temperature and strength of the polymer without affecting its amorphous properties. This is highly beneficial for industrial production to flexibly adjust products according to market demands.

[0030] 2. This invention uses low molecular weight cyclic olefin monomers as raw materials. The optimized cyclic olefin monomers are a combination of tetracyclododecene and tricyclodecene, methylnorbornene, and 2-methyl-tetracyclododecene in a mass ratio of (5-6):(4-5). This ensures the rigidity and transparency of the hydrogenated cyclic olefin polymer product prepared by subsequent addition reaction with dicyclopentadiene followed by olefin hydrogenation.

[0031] 3. This invention utilizes a Ziegler-Natta type catalyst without Ru as the matching catalyst to carry out a ring-opening metathesis polymerization reaction at a temperature of 40-80℃ for 1-3 hours, effectively catalyzing the ring-opening metathesis polymerization reaction of any one of tetracyclododecene, tricyclodecene, methylnorbornene, and 2-methyl-tetracyclododecene, thereby reducing production costs.

[0032] 4. This invention involves a ring-opening metathesis polymerization reaction of low molecular weight cyclic olefin monomers, followed by a quenching reaction to obtain a ring-opening metathesis polymer solution, which is then reacted with dicyclopentadiene in a DA reaction. In particular, the weight ratio of the total weight of the cyclic olefin monomers to the weight of dicyclopentadiene in the dicyclopentadiene solution is controlled to be 100:(0.01-50). Especially when the weight ratio is 100:(0.01-5), the glass transition temperature and elastic modulus of the hydrogenated cyclic olefin polymer product are further improved while avoiding a significant decrease in light transmittance.

[0033] 5. The high-performance hydrogenated cyclic olefin polymer provided by this invention has a glass transition temperature of 130℃-240℃, or no glass transition temperature, and a melting point of 240℃-280℃, which can be effectively applied in the fields of optical devices, optical films, medical packaging materials, and dielectric materials.
