PREPARATION OF ACRYLATE IPN COPOLYMER LATEXES BY RADIATION EMULSION POLYMERIZATION

Radiation-induced and chemical initiation are compared in the initiati on of acrylate emulsion copolymer latexes. The particle diameter, dist ribution and microstructure are influenced by emulsifier concentration , radiation dose and temperature. The results show that the emulsion p article diameter of radiation polymerization is smaller and better dis tributed in comparison to using chemical polymerization. In addition, interlude polymer net (IPN) core-shell copolymer latexes are observed by transimission electron microscope (TEM). The bounding face of core- shell acrylate copolymer latexes of radiation polymerization is cleare r. The morphology of acrylate IPN copolymer latexes is further investi gated.
