POLYPHENYLENE SULPHIDE COMPOSITIONS WITH FINISHED GLASS FIBRES AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2022 - IPC C08L81/04 C08J5/08 C08K7/02 C08K7/14 

FIELD: composite materials.

SUBSTANCE: invention relates to polyphenylene sulphide compositions with finished glass fibres intended as structural polymer materials, and to a method for production thereof. The composition includes polyphenylene sulphide and glass fibre coated with an organic finishing agent - polyhydroxy ether based on 1-chloro-2,3-epoxypropane and 4,4'-dioxy diphenylpropane with a degree of polycondensation n=165÷175. The amount of the finishing agent relative to the glass fibre is 1 to 4 wt.%. The amount of finished glass fibre in the composition is 20 wt.%.

EFFECT: resulting polyphenylene sulphide compositions exhibit improved physical and mechanical properties due to the introduction of a finishing agent enhancing the wettability of the filler and increasing the boundary interactions between the glass fibre and the polyphenylene sulphide matrix.
