Preparation of polymer particles having ethyleneurea groups at their surfaces by emulsifier-free seeded emulsion polymerization and wet adhesion of its emulsion film

摘要

Polymer emulsion having ethyleneurea groups at particle surfaces was produced by emulsifier-free seeded emulsion copolymerization of n-butyl methacrylate (BMA) and methacrylamide ethylethyleneurea (EU) with with poly (BMA) seed particles utilizing the starved-fed monomer addition method.This emulsion film,prepared by casting the polymer emulsion on an alkyd resin plate,had a superior adhesion in water,as well as on stainless steel.Such superior wet adhesions seem to be based on a large amount of EU predominantly localized at the particle surfaces.
