摘要：
The invention provides novel fluoropolymers capable of forming optical elements having low refractive indexes and excellent heat resistance; novel fluorine-containing diene compounds having two unsaturated bonds capable of giving the above fluoropolymers; and light transmitters and plastic optical fibers made by using the fluoropolymers, which exhibit high performance by virtue of the low refractive indexes and excellent heat resistance, specifically, fluorine-containing diene compounds represented by the general formula: CF2=CFCF(ORf)CF2OCF=CF2 [wherein Rf is perfluoroalkyl such as trifluoromethyl]; fluoropolymers of the diene compounds; light transmitters made by using the fluoropolymers; and plastic optical fibers wherein the core is made of a composition comprising a fluoropolymer described above and a low-molecular fluorine compound serving to enhance the refractive index.
