COMPOSITION OF THERMOPLASTIC RESIN Russian patent published in 2001 - IPC

FIELD: facing materials for pipes, pumps, elastic films, working wheel of centrifugal pump, or the like. SUBSTANCE: composition comprises, wt %: component (A), i.e. tetrafluoroethylene homopolymer or perfluorotype copolymer thereof having from 2•10² to 1•10⁵ methylol groups per 1•10⁶ carbon atoms in end group and nw from 5•10² to 5•10⁵, 1-50; component (B), i.e. liquid crystalline polyether and component (E), i.e. tetrafluoroethylene homopolymer or perfluorotype copolymer thereof having no methylol groups in end group or having less that 2•10² methylol groups per 1•10⁶ carbon atoms. Variant of invention is composition comprising in component (C) compound selected from group consisting of polytetrafluoroethylene- hexafluoropropylene copolymer and tetrafluoroethylene- perfluoroalkylvinyl ether copolymer having no methylol groups in end group per 1•10⁶ carbon atoms. Molded products having improved moldability, stability of sizes, deformation resistance and mechanical properties are prepared on the basis of components. EFFECT: improved properties of the thermoplastic composition. 12 cl, 8 ex, 2 tbl
