Abstract

Core particles having iniferter fragments were used as a seed for graft polymerization of 2-hydroxyethyl methacrylate (HEMA) by in the presence of salicylate. A stable PHEMA hairy particle latex was obtained, because sodium salicylate and PHEMA formed hydrophilic complex. The hairy particle was characterized by IR spectrosocopy, and DLS and measurement of electrophoretic mobility. Diameter of hairy particle was almost the same as core particle in water, but the diameter of hairy particle was larger than core particle by 80 nm in a sodium salicylate solution. Result of E.P.M exhibited property of hairy particle.
