丙烯酸甲酯对羧基氯丁胶乳聚合体系的影响
Effect of added methyl acrylate on the polymerization of carboxylic chloroprene emulsion
The influence of added methyl acrylate (MA) on the emulsion copolymerization of methacrylic acid (MAA) and chloroprene in the presence of polyvinyl alcohol as a protective colloid was investigated. It was found that the latex viscosity decreased significantly from 1.36Pa·s to 0.10Pa·s after addition of 30% MA and the particle size of the latex decreased with increasing MA content. A dispersion polymerization mechanism has been proposed in order to account for the effects of added MA on the latex viscosity and particle size.
