To prepare self-emulsifiable urethane acrylate, poly(ethylene glycol)-modified urethane acrylates (PMUA), containing polyoxyethylene chains as a terminal group were synthesized by the reaction of a residual isocyanate group with poly(ethylene glycol) (PEG). Five types of PMUA were synthesized using
Poly(urethane acrylate)/poly(glycidyl methacrylate-co-acrylonitrile) coreshell composite particles were prepared using two-stage emulsion polymerization. Composite particle sizes were varied from 48 to 200 nm by introducing polyoxyethylene groups into the urethane acrylate molecules. The morphology
