PURPOSE:To form a resin compsn. which has good heat resistance, transparency, etc. and a low refractive index and is useful as a light guiding material, by blending an acrylic resin with a vinylidene fluoride/hexafluoroacetone/ tetrafluoroethylene copolymer. CONSTITUTION:This resin compsn. is formed from a vinylidene fluoride/ hexafluoroacetone/tetrafluoroethylene copolymer contg. 2-80wt% (meth)acrylate polymer. Pref. the copolymer has a hexafluoroacetone content of 2-15mol% and a tetrafluoroethylene content of 5-60mol%. Pref. the alkyl group in the (meth)acrylate polymer has 1-4 carbon atoms. |
