Fundamental Studies on the Preparation of Plasticized Synthetic Resin Latices

IV. The Relation Between the Rate of Conversion of Monomer and Transfer of Plasticizer into Polymer Particle

Abstract

In the emulsion polymerization of methyl methacrylate containing DBP in both layer system (non-agitated) and agitated system, the rate of conversion was higher than the rate. of transfer of DBP into polymer particle, and the difference of these rates decreased with increase in emulsifier concentration and decrease in initiator concentration. In the layer system (non-agitated), the ratio of the monomer conversion rate to DBP transfer rate was proportional to the ratio of methyl methacrylate to DBP in oil phase.
