Abstract

A polymer blend comprises a blend of a copolymer of vinylidene fluoride and hexafluoropropylene and from 5 to 50%, calculated on the total weight of the blend, of a crystalline fluoro-, homo- or copolymer or a crystalline homo- or copolymer of ethylene or propylene. Suitable crystalline polymers are polytetrafluoroethylene, polychlorotrifluoroethylene, a fluorinated ethylene or propylene copolymer and polyvinylidene fluoride. Both the copolymers of the blend may be cross-linked. The blend may be used to form articles which have elastic memory, e.g. heat-shrinkable harness moulds for electrical wiring. In the examples, blends comprising (1) polyvinylidene fluoride, magnesium oxide, carbon black, a peroxide and triallyl cyanurate (2-5) polyvinylidene fluoride, magnesium oxide, carbon black, silica, dibasic lead phosphate, a peroxide, zinc oxide, triallyl cyanurate and polyethylene are prepared.
