Abstract
The compositions based on copolymers of vinylidene fluoride and of ethylenically unsaturated fluorine-containing comonomers, containing at least 75% by weight of vinylidene fluoride include polyvinyl chloride and an effective quantity of a methacrylic polymer (producing compatibility). These compositions exhibit in particular improved dielectric properties, which makes them particularly advantageous for sheathing electrical cables.
