摘要：

Polyurethane prepolymer capped by vinyl group (PUV) was synthesized by reaction of hydroxyethyl methacrylate and toluene diisocyanate using di-n-butyltin dilaurate as catalyst, and then polyurethane-poly(butyl acrylate) hybrid latexes were prepared via miniemulsion polymerization of PUV and butyl acrylate (BA). Fourier transform infrared, differential scanning calorimeter were adapted to characterize the structure of PUV and PU-PBA and the properties of their films. The results show that the decrease of BA/PUV ratio result in an increase of the hardness and glass transition (T-g) of PU-PBA, but reduce the stability of miniemulsion and elasticity of final copolymer films.
