| Abstract: | In this paper,a series of the water-borne polyurethane-acrylate hybrid emulsion(WPUA) was synthesized by modifying aqueous polyurethane(PU) with polyacrylate(PA).The effect of content of PU,NCO/OH(initial mole ratio),content of hydrophile chain extender(DMPA) and mass mole ratio of hard-monomer(methyl methacrylate,MMA) to soft-monomer(2-ethylhexyl acrylate,2-EHA) on properties of the WPUA emulsion and its films were systematically studied.The results showed that the WPUA presented the core-shell structure a... |
