Abstract: Urea was added in emulsion-polymerization of Vinyl Acetate（VAc） and N-Hydroxymethyl Acrylamide（NMA）,and some features of the emulsion modified before and after were investigated.Results showed that surface wetting,hardening and wet bond strength of PVAc-NMA-Urea were successfully improved;when the mass rate of urea to VAc was 2.5%～4%,the average contacting angles on Pinus yunnanensis and Pinus koraiensis were the minimum,71.22° and 73.78° respectively;when the mass rate of urea to VAc was 1%～2%,...
