Abstract
The cross-linking acrylic polymer latex based on methyl methacrylate, butyl acrylate, hydroxyethyl methacrylate, and hydroxyethyl acryloylurea was prepared by soap-free emulsion polymerization with sodium 2-acrylamido-2-methylpropanesulfonate and allyloxy alkyl polyoxyethylene ether ammonium sulfate (SR-10) used as the reactive emulsifiers. Glass transition temperature of the latex film prepared is 20°C. The average particle size of the latex is 64 nm and its dispersion index is 0.085. The optimum conditions of preparing the latex were found. In comparison with the conventional latex, the heat and water resistance of the resultant latex have been improved.
