PREPARATION OF POLY(ARYLENE ETHER KETONES)

摘要

An arylene ether ketone copolymer comprising: (a) 99 to 10 mol% of repeat units (I), and (b) 1 à 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 alpha and (II) is -Ph-O-Ph-CO-Ph-O-Ph-CO-Ph-CO-, each Ph independently being m- or p-phenylene.
