PROBLEM TO BE SOLVED: To obtain a compsn. which is excellent in dielectric properties and resistances to heat aging and fire by compounding a specific vinylidene fluoride copolymer, polyvinyl chloride, and a methacrylic polymer. ;SOLUTION: This compsn. comprises (A) a thermoplastic copolymer which is formed from vinylidene fluoride and an ethylenically unsatd. fluorine-contg. comomoner and contains at least 75 wt.% monomer units derived from vinylidene fluoride, (B) polyvinyl chloride, and (C) an effective amt. of a methacrylic polymer, is excellent in dielectric properties and resistances to heat aging and fire, and can be suitably used for covering electric cables.;COPYRIGHT: (C)1996,JPO
