A plastic optical fiber with excellent heat resistance comprising a core made of a polymer comprising units of methyl methacrylate and a cladding made of a polymer containing at least 20% by weight of fluorine is produced by washing the core polymer with an organic solvent in which the core polymer is substantially insoluble, forming the core from the washed core polymer and forming the cladding around the core.
一种具有优异耐热性能的塑料光纤,包括由包含甲基丙烯酸甲酯单元的聚合物制成的芯材和由含氟量至少 20% (按重量计)的聚合物制成的包层,其生产方法是:用芯材聚合物基本不溶于其中的有机溶剂清洗芯材聚合物,用清洗后的芯材聚合物形成芯材,并在芯材周围形成包层。
