摘　　要：通过反相乳化法制备了小粒径的松香乳液 ,以它作为聚合种子 ,采用单体预乳液滴加的半连续乳液聚合方法 ,制备了以松香为核、聚合物为壳的松香 /丙烯酸系复合高分子乳液。并用动态光散射、扫描电子显微镜、差示扫描量热器和凝胶渗透色谱等对所制备的复合高分子乳液进行了表征 ,研究了松香及松香衍生物结构对聚合历程的影响 ,测定了不同松香含量乳液的 1 80°剥离和T型剥离强度 。Rosin-acrylics hybrid latexes were prepared by semi-continuous emulsion polymerization with a rosin emulsion as seed.The hybrid fine-particle rosin emulsion was prepared by inverse emulsification.The hybrid polymer latexes were characterized with dynamic light scattering,SEM,DSC and GPC.Effects of the structure of rosin and rosin derivatives on polymerization as well as the 180° and T-peel strength of latexes obtained were investigated.Results shows that introduction of rosin derivatives improves remarkably the bonding properties of acrylic polymers.
