Abstract: 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.

Abstract: PCT No. PCT/EP90/00585 Sec. 371 Date Nov. 7, 1991 Sec. 102(e) Date Nov. 7, 1991 PCT Filed Apr. 13, 1990 PCT Pub. No. WO90/12043 PCT Pub. Date Oct. 18, 1990.A transparent thermoplastic molding compound consisting of 40 to 90% by weight of units derived from tetrafluoroethylene, and 60 to 10% by weight of units derived from compounds of formula I or II: CF2=CF-O-(CF2-CF(CF3)-O)m-(CF2)n-CF3(I) CF2=CF-O-(CF2-CF(CF3)-O)p-(CF2)q-COO-R(II) is particularly suitable for manufacturing the sheath of beam waveguides whose core has a higher transparency than polymethyl methacrylate.

Abstract: of the disclosure: HOE 86/F 049 Optical waveguides of plastic usually consist of a core and a jacket, the core material having a higher refractive index than the jacket material. A suitable core material is a fluorine-free polymer and a suitable jacket material is a fluorine-containing polymer, which can also contain deuterium. The optical waveguides can be produced by passing a polymer rod through a solution of the jacket polymer and then removing the solvent. The optical waveguides are particularly suitable for the transmission of data with the aid of light waves with a wavelength of 500 to 750 nm.
