Moulding composition, useful for production of fibres, film and moulded articles

摘要

A moulding composition (I) is prepared by mixing (A) 1-98 wt.% of a polyarylene ether having repeating units of formula (1); (B) 1-98 wt.% of a thermoplastic styrene copolymer; (C) 1-20 wt.% of an oligomeric phosphorous compound; (D) 0-60 wt.% of a polycarbonate; (E) 0-50 wt.% of a toughening rubber; (F) 0-60 wt.% reinforcing agent and/or filler; and (G) 0-50 wt.% ether additive. In (1), the repeating unit is optionally substituted with 1-6C alkyl or 1-6C alkoxy; X = -SO2-, -SO-, -O-, CO, -N=N-, RC=CRa-, -CRbRc- or a chemical bond; Z = -SO2-, -SO-, -N=N- or -RC=CRa-; R, Ra = H or 1-6C alkyl; and Rb, Rc = H, 1-6C alkyl, 4-10C cycloalkyl, 1-6C alkoxy or aryl or fluoro- or chloro-derivatives. Also claimed are (i) fibres, film or moulded articles prepared from (I); and (ii) a process for the production of fibres, film or moulded articles by extrusion, blow moulding or injection moulding of (I).
