Abstract
A thermoplastic composition comprising a poly(arylene ether), a polyolefin, and a polymeric compatibilizer selected from the group consisting of (i) a block copolymer wherein a central block is a controlled distribution copolymer, and (ii) a polypropylene-polystyrene graft copolymer; is disclosed. The composition is useful in the production of covered wire.
Claims25
A thermoplastic composition comprising:
- a poly(arylene ether) having an initial intrinsic viscosity greater than 0.25 dl/g as measured in chloroform at 25° C.;
- a polyolefin having a melt temperature greater than or equal to 120° C. and a melt flow rate of 0.3 to 15;
- and
- a polymeric compatibilizer selected from the group consisting of
- (i) a block copolymer wherein a central block is a controlled distribution copolymer, and
- (ii) a combination of a polypropylene-polystyrene graft copolymer and a block copolymer;
- wherein the poly(arylene ether) is present in an amount by weight greater than the amount of polyolefin by weight.
