ABSTRACT:
A thermoplastic molding composition having a light transmission value of at least 40% is disclosed. The composition contains a thermoplastic polyurethane component, a styrene copolymer, and an alkyl(meth)acrylate component and is characterized by the compatibility of its components. The weight ratio between the styrene copolymer to the sum of the styrene copolymer and alkyl(meth)acrylate components was found to be critical to the light transmission of the inventive composition.
