Abstract
A flexible thermoplastic composition comprises a poly(arylene ether), a first block copolymer, a second block copolymer and a flame retardant wherein the second block copolymer comprises a controlled distribution copolymer block. The flexible thermoplastic composition is useful in the manufacture of coated wires.
Claims27
A flexible thermoplastic composition comprising
- a poly(arylene ether),
- a first block copolymer,
- a second block copolymer,
- and a flame retardant
- wherein the first block copolymer is selected from the group consisting of polyphenylethylene-poly(ethylene/propylene), polyphenylethylene-poly(ethylene/propylene)-polyphenylethylene, and polyphenylethylene-poly(ethylene/butylene)-polyphenylethylene,
- the second block copolymer comprises a block that is a controlled distribution copolymer having terminal regions that are rich in alkylene units and a center region that is rich in alkylene units,
- wherein the composition has an ultimate elongation greater than or equal to 100% and less than or equal to 500% according to UL 1581, and
- further wherein the flame retardant comprises a phosphinate.
A coated wire comprising an electrically conductive core at least partially covered by a flexible thermoplastic composition comprising a poly(arylene ether), a first block copolymer, a second block copolymer and a flame retardant wherein the first block copolymer is selected from the group consisting of polyphenylethylene-poly(ethylene/propylene), polyphenylethylene-poly(ethylene/propylene)-polyphenylethylene, and polyphenylethylene-poly(ethylene/butylene)-polyphenylethylene, the second block copolymer comprises a block that is a controlled distribution copolymer having terminal regions that are rich in alkylene units and a center region that is rich in aryl alkylene units, wherein the composition has an ultimate elongation greater than or equal to 100% and less than or equal to 500% according to UL 1581, and further wherein the flame retardant comprises a phosphinate.
