Preparation and Characterization of Polyacrylate Emulsion

摘要

In this paper, polyacrylate emulsion was prepared by using methyl methacrylate (MMA) and butyl acrylate (BA) as polymerization monomer and acrylic acid (AA) as functional monomer via seed pre-emulsification method. The effects of emulsifier dosage, rotated speed and temperature on the properties of acrylate emulsion were studied. The results showed that the optimum condition was as follows: the emulsifier content was 3%, the pre-emulsification speed was about 480 r/min, the polymerization speed was 250 r/min, the pre-emulsification temperature was about 35 ℃, and the reaction temperature was about 80 ℃.
