Prepartion of acrylate IPN copolymer latexes by radiation emulsion polymerization

摘要

Radiation-induced and chemical initiation are compared in the initiation of acrylate emulsion copolymer latexes. The particle diameter, distribution and microstructure are influenced by emulsifier concentration, radiation dose and temperature. The results show that the emulsion particle diameter of radiation polymerization is smaller and better distributed in comparison to using chemical polymerization. In addition, interlude polumer net (IPN) core-shell copolymer laterxes are observed by transimission Eletron microscope 9TEM). The bounding face of core-shell acrylate copolymer latexes of radiation Polymerization is clearer. The morphology of acrylate IPN copolymer latexes is further investigated.
