| abstract |
PCT No. PCT/GB88/01012 Sec. 371 Date Jun. 29, 1990 Sec. 102(e) Date Jun. 29, 1990 PCT Filed Nov. 17, 1988 PCT Pub. No. WO89/04848 PCT Pub. Date Jun. 1, 1989.An arylene ether ketone copolymer comprising: (a) 99 to 10 mol % of repeat units <IMAGE> (I) and (b) 1 to 90 mol % of repeat units -Ar-O-Ar-CO- (II), wherein each Ar independently is m- or p-phenylene or a di- or poly- m- and/or p-phenylene moiety in which the phenylene rings are linked together by direct bonds or by -O- or -CO- groups. Especially preferred are the copolymers wherein (I) is <IMAGE> and (II) is -Ph-O-Ph-CO-Ph-O-Ph-CO-Ph-CO-, each Ph independently being m- or p-phenylene. |
