Abstract
New and novel copolymers of vinylidene fluoride and hexafluoropropylene containing up to about 24% by weight hexafluoropropylene having improved solution clarity and fluidity, longer gel times and lower extractables than prior art vinylidene fluoride-hexafluoropropylene copolymers of comparable HFP content whose syntheses are disclosed in sufficient detail to duplicate, the novel compositions of matter and articles of manufacture containing such copolymers, of the compositions of matter containing such copolymers and of the articles of manufacture containing such copolymers are disclosed. Also disclosed are novel battery constructions based on the novel copolymers of vinylidene fluoride/hexafluoropropylene copolymers of the invention, on vinylidene fluoride homopolymers having a bimodal molecular weight distribution and on vinylidene fluoride/chlorotrifluoroethylene copolymers having a substantially homogeneous monomer distribution.
