摘　　要：用自由基聚合法合成了大分子单体聚N 乙烯甲酰胺和功能高分子微球 .用GPC、分光光度仪和扫描电子显微镜等对合成的聚合物进行了表征 .研究结果表明 ,大分子单体聚N 乙烯甲酰胺和功能高分子微球具有明显的热敏性特性 ,且合成的功能高分子微球具有单分散性 ,粒径在 1～ 5Macromonomer poly(N-vinylformamide) and functional polymer microspheres are synthesized by radical polymerization, respectively. The properties of the macromonomer and the functional polymer microspheres have been studied by GPC, spectrophotometer and SEM. The results indicate that the macromonomer and the microspheres possess definite properties of thermo-sensitivity. Moreover the functional polymer microspheres have monodispersibility and its particle diameter is in the range of 1 similar to 5 mum.
