摘要: Various waterborne interpenetrating polymer networks (IPNs) composed of polyurethaneurea (PUU) and graft vinyl ester resin were prepared from polyester polyol, dimethylolpropionic acid, isophorone diisocyanate, ethylenediamine a well-defined containing butanol side chains (BO-g-VER). These anionic IPN aqueous dispersions stable at the ambient temperature for >1 yr, also had excellent stability low high temperatures. The experimental results showed that introduction BO-g-VER network has not only greatly affected particle morphology, rheological behavior these dispersions, but rendered films with augmented surface hydrophobicity as well water-resistance performance mechanical properties. A synergistic effect was observed certain composition (20 wt %) to give significant reinforcement PUU, resulting compatibility and/or interpenetration between PUU network. © 2009 Wiley Periodicals, Inc.
