Abstract
The present invention relates to a polymer composition comprising a polymer comprising methyl methacrylate, (meth)acrylic acid and styrene monomers. In particular, the present invention relates to a polymer composition comprising a polymer comprising methyl methacrylate, (meth)acrylic acid and styrene monomers, said composition having particularly advantageous compromises of heat-resistant, fluidity, scratch-resistant and chemical-resistant properties. The present invention also relates to a molded or extruded object comprising a polymer comprising methyl methacrylate, (meth)acrylic acid and of styrene monomers, and the use of these objects.
