The invention relates to a novel UV-protective and weather-resistant package for surface protecting films for polyvinyl chloride window profiles made of poly(meth)acrylate. Matrix plastics having great molecular weights are used in order to obtain great weather resistance of the surface protecting films.

PMMA film featuring particularly great weather resistance and great UV protection

The invention relates to a molded body consisting of plastic with a material thickness of at least 150 $g(m)m at any point. Said body contains a polymer mixture of an impact-resistance modified poly(meth)acrylate plastic, a polymethyl methacrylate matrix, elastomer particles contained in said matrix and a fluoropolymer. According to the invention, the fraction of the fluoropolymer in the mixture is between 30 and 95 wt. % and the polymer mixture of the impact-resistance modified poly(meth)acrylate plastic and the fluoropolymer is present in an outer layer with a continuous material thickness of at least 10 $g(m)m. The invention is characterized in that the impact-resistance modified poly(meth)acrylate plastic consists of between 20 and 70 wt. % poly(meth)acrylate matrix and between 30 and 80 wt. % elastomer particles.

The invention describes a novel impact modifier, built up from core-shell1- and shell 2, the core being capable of plastic deformation. Good mechanical properties were achieved using a small amount of impact modifier.

PMMA moulding compounds with improved impact resistance

The invention relates to a novel impact-resistance modifier, constructed from a core-shell 1 and a shell 2, whereby the core is plastically deformable. The invention is characterised by excellent mechanical properties obtained by a low content of impact-resistance modifier.
