Research output: Chapter in Book/Report/Conference proceedingConference contribution


Core particles having iniferter fragments were used as a seed for graft polymerization of 2-hydroxyethyl methacrylate (HEMA) by living radical mechanism. As a result, a stable PHEMA hair particle latex was obtained.High stability was attributed to that sodium salicylate (NaSal) and PHEMA formed hydrophilic complex. The particle was characterized by IR spectrosocopy, and DLS and measurement of electrophoretic mobility. In addition, the release behavior of NaSal was examined.
