Problems solved by technology

When the proportion of ketone-containing monomers is greater than 30% of the sum of sulfone-based monomers and ketone-based monomers, the polymerization reaction will be more difficult, and the cycle of polymerization production will be longer, which will cause the problem of high color and melting point of the product, especially When the proportion of ketone-containing monomers is greater than 40% of the sum of sulfone-based monomers and ketone-based monomers, the polymerization reaction hardly occurs at a temperature lower than 240°C
When the proportion of the ketone-containing monomer is greater than 25% of the sum of the sulfone-based monomer and the ketone-based monomer, the Tm of the obtained random copolymer is greater than 350°C, and the processing temperature of the resulting product will also reach 380°C or higher , resulting in difficult processing and difficult to be widely used
In addition, the transparency of its products will also decline to a certain extent.

Embodiment 1

[0034]In a 200-liter stainless steel reaction kettle equipped with a nitrogen pipe, a condensing water separator and a high-efficiency stirrer, first add 100.00KG sulfolane and start stirring to raise the temperature to 80°C, and then add 20.88KG 4,4'-dichlorodiphenyl Sulfone, 1.57KG 4,4'-difluorobenzophenone, 15.00KG 4,4'-biphenyldiol, after the monomers are completely dissolved, add 9.50KG sodium carbonate to the system when the temperature rises to 100°C, Then add 9.0 liters of mesitylene; continue to stir and heat up to 200°C, the salt-forming reaction begins, the water generated in the system azeotropes with mesitylene, cooling water begins to drip from the condenser tube, and layers are separated in the water separator. After the upper layer of mesitylene turns from turbid to clear, continue to reflux for 20 minutes to ensure that the salt formation reaction is complete. The salt formation stage is about 1 hour; after the salt formation is completed, raise the temperature...

Abstract

The invention discloses a high-fluidity polyphenylene ether sulfone ketone (PPSUK) resin which is implemented through introducing an aromatic ketone monomer, especially a heterogeneous aromatic ketone monomer copolymer, into a PPSU polymer, so that the main chain of an obtained copolymer molecule contains a polyether sulphone and polyaryletherketone random copolymer structure, wherein the molar ratio of groups is (5-9):1. The machine-shaping temperature of a polymer prepared by using the method disclosed by the invention is usually not higher than 350 DEG C, and the polymer is high in fluidity and easy to machine, and has excellent solvent resistance, thereby expanding the product application field.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high fluidity polyphenylene ether sulfone ketone resin PPSUK and an industrial synthesis method thereof. Background technique [0002] Polyaryl ether sulfone is a kind of high-performance engineering plastics, because of their excellent comprehensive properties such as heat resistance, hot water resistance, creep resistance, dimensional stability, impact resistance, chemical resistance, non-toxicity, flame retardancy, etc. Therefore, it has been widely used in the fields of electronics, electrical appliances, machinery, automobiles, medical appliances, food processing and non-stick coatings for a long time. [0003] Industrially important polyarylethersulfones include polyethersulfone (PES) and biphenyl polyethersulfone (PPSU), both of which have high glass transition temperatures (~220 °C). In the process of use, due to the high melt viscosity of polyary...
