| Abstract: | Acrylic acid modified water soluble polyurethane emulsion (PUA) was prepared by graft method. The influence of dimethylolpropionic acid(DMPA) and methyl methacrylate(MMA) on water absorption,viscidity and film hardness of PUA emulsion were studied and characterized difference in molecular structure between water soluble PUA,water soluble PU and cross blend PU/ PA by infrared analysis. |
