AN INVESTIGATION OF THE RADIATION POLYMERIZATION OF METHYL METHACRYLATE-KAOLIN CLAY COMPOSITES

摘要

A kinetic and characterization study has been made on the effects of gamma -rays (Go 60) on the polymerization of a 50-50 weight mixture methyl methacrylate (MMA) kaolin clay system. The effect of dose rate (7.35 - 24.9 rads per second), temperature (25 to.75°C) and total dose on the percentage conversion of monomer to polymer was studied. The rate o of formation of polymer at 25 C in the composite system was found to be faster when compared to a bulk MMA system at the same experimental conditions.
