Fundamental Studies on the Preparation of Plasticized Synthetic Resin Latices

A Comparison of the Emulsion Polymerization of Methyl Methacrylate in the Layer System and in the Agitated System

Abstract

Methyl methacrylate polymer was prepared by emulsion polymerization in both layer system (L) and agitated system (A). The rate of conversion and the molecular weight of the polymer in L were extremely lower than in A, and the number of polymer particle in L was greater than in A. These phenomena were discussed from the difference of the rate of monomer supply to polymer particle between L and A.
