THERMOPLASTIC POLYMER COMPOSITION Russian patent published in 1996 - IPC

FIELD: manufacturing details having various construction purposes. SUBSTANCE: proposed composition contains (mass parts): polycarbonate 45-70, polyalkylene terephthalate 20-50, liquid crystal copolymer of ethylene terephthalate and p-oxybenzoic acid (mass ratio of monomeric unit in said copolymer is 20:80-40:60) 5-9. Proposed composition may also contain 1-20 mass part of graft copolymer of butadiene, styrene and acrylonitrile. Thus prepared composition is dried at 120 C to residual humidity not more 0.02 %. Desired samples are prepared by pressure-die casting. EFFECT: improves quality of desired product. 2 cl, 2 tbl
