PMMA/PVDF FILM WITH PARTICULARLY HIGH WEATHERING STABILITY AND HIGH UV PROTECTIVE ACTION

摘要

The present invention, which describes a kind of transparent membrane, has high weatherability and stability by polymer, and improves inherent stability, and wherein film includes) poly- (methyl) acrylate and polyvinylidene fluoride ratio be from 1:0.The ultra-violet stabilizer and UV absorbents of the mixture of 01 to 1:1 (weight) and step b). Weathering stability is not being paid off in order to obtain, and is improving the surface protection film of inherent stability, and preference, which is given, uses PMMA matrix polymers to have high molecular weight and regioselective coacrylate contents.
