Vinyl Acetate Copolymers with Vinylidene Fluoride and Hexafluoropropene by UV Mediated Peroxide Irradiation at Room Temperature

摘要

Poly(vinylidene fluoride) (PVDF) 1 is a widely used high- performance polymer for coating,semiconductor or nuclear applications due to its excellent chemical inertness,acid resistance,low water absorptivity,weatherability,low dielectric constant and piezoelectric properties. 2 - 4 Its application in proton-conductive membranes has also been attracting attention recently.5 However,in spite of many useful properties,the high crystallinity and low solubility of PVDF limit certain practical uses.12
