摘要： New polymeric compositions based on polytetramethylene terephthalate (PTMT) polymers are disclosed. PTMT polymers are subject to embrittlement, especially at elevated temperatures and when a flame retardant is incorporated therein. This problem is substantially reduced by blending the PTMT polymer with a second polymer which has a flex modulus of 500 to 100,000 psi and a solubility parameter within .+-.1.5 of the PTMT polymer, for example an ethylene/vinyl acetate copolymer or a block copolymer containing polyether and polyester blocks. The compositions are particularly useful as wire insulation.

摘要： Shaped articles of cross-linked polymers comprising a first component having little or no cross-linking and high elongation, and a second component having a relatively high level of cross-linking and low elongation. Such articles are particularly useful in the form of electrical insulation, the first component being adjacent to a wire or other conductor. Preferably each of the components comprises a crystalline fluorocarbon polymer, especially an ethylene/tetrafluoroethylene copolymer. Such articles can be prepared by (1) melt-extruding a first polymeric composition which contains little or no cross-linking agent, and a second polymeric composition which contains a greater amount of cross-linking agent, (2) maintaining the two extrudates under conditions such that cross-linking agent migrates from the second to the first composition, and (3) cross-linking both compositions, preferably by radiation.

摘要： Electrical insulation comprises (1) an inner layer of a cross-linked polymer, e.g. polyethylene, an ethylene/tetrafluoroethylene copolymer, an ethylene/chlorotrifluoroethylene polymer or a vinylidene fluoride polymer, and (2) an outer layer of an aromatic polymer having a glass transition temperature of at least 100.degree. C., e.g. a polyether ether ketone, a polyether ketone or a polyether sulfone. Such insulation combines excellent properties under normal service conditions with low smoke evolution on burning, and is therefore particularly useful for aircraft wire and cable.
