β¦ Synopsis
The possibility of obtaining high-solids-content microlatexes was investigated. It was found that, for the semicontinuous copolymerization of methylmethacrylate and butylacrylate coagulum-free 45.20% solid content latexes can be obtained through microemulsion polymerization using Dowfax 2A-1 surfactant. The effect of the amount of surfactant, type of cosurfactant, type and concentration of initiator and temperature on solid content was studied. The chemical, freeze-thaw, storage and mechanical stabilities of the latexes were determined.

Polymer lattices with a multimodal particle size distribution (PSD) polymer latex were prepared by introducing additional surfactants during the semicontinuous emulsion polymerization of styrene, butyl acrylate, and methacrylic acid. The polymerization was investigated by following the variation of
