【摘要】 本文以聚氨酯水分散体作为种子乳液,利用乳液互穿网络这种聚合物改性技术,成功地合成出一系列不同结构的聚氨酯/聚丙烯酸酯复合乳液。研究了复合乳液粒子形态的预测方法,即利用测定复合乳液膜与水的接触角,来确定本研究中复合乳液粒子的形态,同时测定乳液膜与辛烷、水的界面的接触角,来计算复合乳液膜表面的极性组分,通过表面极性来预测乳液粒子的形态。更多还原

【Abstract】 An investigation of sereral composite latexes consisting of polyurethane polymers and acrylic polymers is the subject of this paper The composite latexes were synthesized by latex interpenetrating polymer networks technology,in which polyurethane polymers were slightly cross-linked and used as"seed"latex.The morphology prediction of composite latexes was investigated by the measured surface polarity of latex films which was estimated by contact angle measuremeat at the latex"film"/water interface for octane as the probe liquid,and the predicted morphologies were compared with the measured particle morphologies of the composite latexes which was estimated by contact angle of a water drop at the latex film surface.更多还原
