Abstract:
A thermoplastic molding composition consisting essentially of a homogeneous blend of(i) a block copolycarbonate conforming structurally to ##STR8##wherein n is an integer of 1 to 1000, m is an integer of about 1 to 500, p is an integer of about 1 to 10, A is a derivative of an aromatic dihydroxy compound, R and R' are C.sub.1 -C.sub.20 alkyl or C.sub.6 -C.sub.14 aryl radical and(ii) about 2 to 10 percent relative to the weight of said blend, of a partially fluorinated polyolefin having a number average molecular weight of 30,000 to 1,000,000 as determined by gel permeation chromato-graphy selected from the group consisting of poly(vinylidene fluoride), polyvinylidene difluoride, poly(vinylfluoride), poly(trifluoroethylene), poly(chlorotrifluoroethylene) and poly(trifluoroethylene alkali metal sulfonate),said composition having a flame retardance rating of V-0 in accordance with UL-94 @ 1/8"", said rating being achieved in the absence of additional flame retarding agents.
