POLYPHENYLENE SULFONE BASED COMPOSITE MATERIAL AND A METHOD FOR PRODUCTION THEREOF Russian patent published in 2019 - IPC C08L81/06 C08K3/34 B29C41/02 B29C64/10 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to a method of producing a composite material based on polyphenylene sulfone, used as superconstructive polymer material for additive 3D technologies. Method of producing the composite material involves preliminary drying mixture of 75–85 wt% polyphenylene sulphone and 10 wt% filler extruded and granulated. Further, the filled polyphenylene sulfone granulate is mixed with granules of polycarbonate used as a plasticiser. Then produced mixture is extruded. Polycarbonate is taken in amount of 5–15 wt%. Filler used is talc.

EFFECT: invention increases impact strength and modulus of elasticity of the composite material.
