Title:
SULFONE POLYMER COMPOSITION, PREPARATION METHOD THEREFOR AND THERMOPLASTIC MOLDING COMPOSITION COMPOSED THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/193478
Kind Code:
A1
Abstract:
Disclosed are a sulfone polymer composition, a preparation method therefor and a thermoplastic molding composition composed thereof. The sulfone polymer composition comprises: (A) at least one aromatic sulfone polymer; and (B) a 4,4'-dichlorodiphenyl sulfone compound; wherein the weight content of 4,4'-dichlorodiphenyl sulfone is less than 600 ppm based on the total weight of the sulfone polymer composition. The preparation method therefor includes using sulfolane as a solvent, 4,4'-dichlorodiphenyl sulfone and 4,4'-dihydroxy diphenyl sulfone or 4,4'-dihydroxybiphenyl as a reaction monomer, and a mixed salt of sodium carbonate and potassium carbonate as a salifying agent, and using the solution polymerization technology to perform polymerization so as to obtain the sulfone polymer composition. The light transmittance of the sulfone polymer composition is more than 85%, the haze is less than 4%, the yellowness index is less than 5, and the sulfone polymer composition has improved transparency and color level.
