Embodiment 1

[0042] In the three-necked flask equipped with a thermometer, a nitrogen pipe, a condensing water separator, and a stirrer, 125.15g (0.5mol) of 4,4'-dihydroxydiphenylsulfone and 147.17g (0.5125mol) of ) 4,4'-dichlorodiphenyl sulfone, then add 426g sulfolane solvent, stir and heat up to 80°C to dissolve the monomer until the solution is transparent, add 55.65g sodium carbonate, then add 80mL xylene, continue stirring and heat up to 140°C Under certain conditions, the salt-forming reaction begins, and the azeotrope formed by the water and xylene produced in the system is blown out into the condenser by the protective gas, and the condensation drops to the water separator for stratification, and the xylene in the upper layer flows back into the system Keep the temperature in the range of 200°C-210°C, when the collected water yield is close to the theoretical value (9g), continue to reflux for 20 minutes, and no water drops are observed, which proves that the salt formation is comp...

Embodiment 2

[0047] The method is basically the same as in Example 1, except that the monomer 4,4'-dihydroxydiphenylsulfone (bisphenol S) is replaced by 125.13g (0.5mol) of 4,4'-dihydroxybiphenyl, and then 426g Sulfolane solvent, after heating up and dissolving, add 80mL of water-carrying agent xylene, 55.65g of salt-forming agent sodium carbonate, control the temperature of water-carrying at 180°C until no water is formed, continue to heat up to 190°C, keep warm for 1 hour, and separate by heating Xylene is produced, and the polymerization temperature is in the range of 210°C-230°C to obtain the polyphenylsulfone polymer PPSU material. The performance characterization comparison data is shown in the table below.

Embodiment 3

[0049] The method is basically the same as in Example 1, except that 4,4'-dihydroxydiphenylsulfone (bisphenol S) is replaced by 114.14g (0.5mol) of 2,2-bis(4-hydroxyphenyl)propane, and then Add 426g of sulfolane solvent, heat up and dissolve, add water-carrying agent xylene 80mL, salt-forming agent sodium carbonate 55.65g, and control the temperature of water-carrying at 180°C until anhydrous is formed, continue to heat up to 190°C, and keep warm for 1 hour. (Bisphenol A polymerization temperature ranges from 200°C to 220°C to obtain polysulfone polymer PSU material. Performance characterization comparison data are shown in Table 1 below.

Abstract

The invention provides a sulfone polymer composition and a preparation method thereof. The composition comprises at least one aromatic sulfone polymer and an alkali metal salt; the weight of the saltin the sulfone polymer composition is controlled to be less than 50 ppm, and the content of the salt in the sulfone polymer composition has a significant influence on the transparency and color of resin. The light transmittance of the sulfone polymer composition is more than 85%, the haze of the composition is less than 3%, and the transparency and color of the sulfone polymer composition can be remarkably improved. The sulfone polymer composition is widely applied to products with high temperature resistance, solvent resistance and transparent conditions in the fields of aerospace, medical treatment and public health, food safety, household electrical appliances, electronic appliances and energy and chemical application.

Description

Technical field: [0001] The invention relates to the technical field of special engineering plastics, in particular to a high-temperature-resistant transparent thermoplastic engineering plastic sulfone polymer and its composition and method for applications in food contact, electronic appliances, aerospace, medical and health care, and the like. In particular, a sulfone polymer composition and a preparation method thereof. Background technique: [0002] Sulfone polymer is a high-performance engineering plastic. Due to its excellent comprehensive properties such as thermal properties, hot water resistance, creep resistance, dimensional stability, impact resistance, chemical resistance, non-toxicity, and flame retardancy, The sulfone polymers currently used mainly include three types: polysulfone PSU, polyethersulfone PES and polyphenylsulfone PPSU. It has been developed for more than 50 years since it was developed in the 1970s. With the improvement of material development, ...
