Abstract
A blend polymer composition, which is superior to polyvinylidene fluoride (PVDF) in impact resistance and retains favorable properties of PVDF, is obtained by blending 1-100 parts, and preferably 1-50 parts, by weight of a copolymer of vinylidene fluoride (VDF) and hexafluoroacetone (HFA) with 100 parts by weight of PVDF. Preferably the mole ratio of copolymerized VDF to HFA is from 96:4 to 50:50.
