摘要：
The emulsion polymerization of methyl methacrylate (MMA) with butyl acrylate (BA) using aqueous polyurethane dispersion as seed was undertaken to prepare acrylic-polyurethane (PUA) hybrid emulsions with high solid content. The concentrations of the anionic groups were varied by adding different amount of dimethylolpropionic acid (DMPA). The emulsions with a similar bimodal particle size distribution (PSD) were obtained. The viscosity of the emulsions is about 350 mPas while the solid content is about 55%.
