PCT No. PCT/EP90/00587 Sec. 371 Date Dec. 12, 1991 Sec. 102(e) Date Dec. 12, 1991 PCT Filed Apr. 12, 1990 PCT Pub. No. WO90/12040 PCT Pub. Date Oct. 18, 1990.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.
