Abstract: Homopolymers and copolymers of fluoroalkyl methacrylate are the important materials for plastic optical fiber. In this paper the method of the monomer synthesis and the homo- and the copoly-merization condition were reported. Polymers with high molecular weight are obtained by using this method. The theoretically calculated results of the refractive index of the polymers according to the theory of group contribution are in agreement with those of the practical measurements. The Mark-Houwink equations [η]_{THF^25℃=3.54×10^-3×M^0.73, [η]Acetone^25℃=2.34×10^-3×M^0.75 of the homopolymer are identified by measuring with light scattering and viscosity.}
