AbstractIt was previously reported that excellent mar resistance coating systems could be obtained by the combination of silicone compounds and vinyl compounds, such as KBM 403–GMA systems. Radiation‐induced polymerization was the most efficient means of prepolymerization of give the viscosity suitable for coating. In this report, change in conversion and the predominant mechanims of prepolymerization were investigated by measuring the change in refractive index. It was shown that the conversion change and the predominant prepolymerization mechanism could be identified by the refractive index. The relationship between the refractive index and coating properties such as film thickness and haze value was also studied. Dripping of GMA prepolymer occurred, and coating thickness was small in GMA including prepolymer systems obtained predominantly by radical mechanism; the thickness was relatively large in the prepolymer systems obtained by epoxy ring opening‐type polymerization mechanism. However, the mar resistance in the former was excellent in spite of reduced thic
