Embodiment 1

[0017] Example 1: Mix 0.1mol trimethylolpropane with 0.3mol gallic acid, add pyridine to dissolve, add p-toluenesulfonic acid with 3% total reactant mass, stir at 120°C for 4 hours, remove under reduced pressure at 10KPa Pyridine yields hydroxyl-terminated hyperbranched polymers. Mix the hydroxyl-terminated hyperbranched polymer and lauric acid, wherein the molar ratio of the hydroxyl group of the hydroxyl-terminated hyperbranched polymer to the carboxyl group of lauric acid is 1:2, add pyridine to dissolve the reactant, and then add 3% p-toluene of the total reactant mass Sulfonic acid was reacted at 120°C for 6 hours to obtain a crude product. The obtained crude product was dissolved in 20 mL of chloroform, and then the solution was added dropwise to 50 mL of deionized water for precipitation, and the lower layer solution was removed under reduced pressure at 10 KPa to remove the solvent chloroform, and the obtained pale yellow solid was an aromatic hyperbranched surfactant....

Embodiment 2

[0019] Example 2: Mix 0.1mol trimethylolethane with 0.6mol gallic acid, add pyridine to dissolve, add concentrated sulfuric acid with 5% total reactant mass, stir for 3 hours at 110°C, remove pyridine under reduced pressure at 30KPa A hydroxyl-terminated hyperbranched polymer is obtained. Mix the hydroxyl-terminated hyperbranched polymer with palmitic acid, wherein the molar ratio of the hydroxyl-terminated hyperbranched polymer to the palmitic acid carboxyl group is 1:1, add pyridine to dissolve the reactant, and then add concentrated sulfuric acid with 5% of the total reactant mass , reacted at 110° C. for 4 hours to obtain a crude product. The obtained crude product was dissolved in 50 mL of chloroform, and then the solution was added dropwise to 200 mL of deionized water for precipitation, and the lower layer solution was removed under reduced pressure at 12 KPa to remove the solvent chloroform, and the obtained pale yellow solid was an aromatic hyperbranched surfactant. ...

Abstract

The invention provides a hyperbranched polymer surfactant and a preparation method thereof, in particular to a preparation method of an aromatic hyperbranched polymer surfactant. Using gallic acid and polyhydroxy monomers to synthesize hydroxyl-terminated hyperbranched polymers in a "one-step method", and then perform esterification reaction with long-chain unsaturated fatty acids or saturated acids and hydroxyl-terminated aromatic hyperbranched polymers to obtain the aromatic Hyperbranched polymeric surfactants. The aromatic hyperbranched polymer surfactant of the present invention adopts common natural multi-terminal monomer gallic acid to react with polyhydroxy monomers, and the surface active agent obtained by esterification has both traditional small-molecule surfactants and can reduce the surface activity of water. characteristics, and has a unique molecular structure of hyperbranched polymers, making it a new type of surfactant in the field of surfactants.

Description

technical field [0001] The invention provides a hyperbranched polymer surfactant and a preparation method thereof, in particular to a preparation method of an aromatic hyperbranched polymer surfactant. Background technique [0002] Hyperbranched polymers are a class of highly branched macromolecules. Although their structures are not as perfect as dendrimers, their physical and chemical properties are similar to those of dendrimers. For example, there are a large number of active functional groups at the ends, good Solubility, low melt viscosity, no chain entanglement, etc. In addition, the synthesis of hyperbranched polymers does not require strict protection / deprotection steps, which is simpler than the synthesis of dendrimers, and it is possible to achieve large-scale industrial production and has great application potential. Therefore, people are interested in the development of hyperbranched polymers. Research has shown a lot of interest. Through the surface grafting ...
