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

摘要

The invention describes a transparent film composed of polymer with high weathering stability and increased intrinsic stability, wherein the film comprises a) poly(meth)acrylate and polyvinylidene fluoride in a ratio of from 1 : 0.01 to 1 : 1 (w/w) and b) a mixture of UV stabilizers and UV absorbers. In order to achieve outstanding weathering stability and increased intrinsic stability of the surface protection films, preference is given to using PMMA matrix polymers with high molecular weights and a particular selected coacrylate content.
