Abstract

Transparent thermoplastic molding compound made of 2,3-difluoroacrylic acid esters. A thermoplastic molding compound consisting of units of 2,3-difluoroacrylic acid esters or their deuterated derivatives, or containing units of these esters, is distinguished by a high glass transition temperature and a high transparency. It is therefore suitable for the manufacture of beam waveguides for long transmission distances and high continuous use temperatures.
