    • The present invention relates to a method of synthesizing a bigraft compolymer based on grafted type peracid polymer, which comprises graft polymerizing a first ethylenically unsaturated monomer containing a carboxyl group onto a polymer substrate having a form of a membrane, particulate or tube; oxidizing the carboxyl groups of the resulting graft polymer into peracids; and then graft polymerizing a second ethylenically unsaturated monomer onto the grafted chain of the graft polymer through the decomposition of the peracid. Surface profile and morphology of the bigraft copolymer membrane product is also investigated by scanning electron microscopy and transmission electron microscopy respectively.
    • 本发明涉及一种基于接枝型过酸聚合物合成一种载体聚合物的方法,该方法包括将含有羧基的第一种烯属不饱和单体接枝聚合到具有膜,颗粒或管形式的聚合物基材上; 将所得接枝聚合物的羧基氧化成过酸; 然后通过过酸分解将第二种烯属不饱和单体接枝聚合到接枝聚合物的接枝链上。 还通过扫描电子显微镜和透射电子显微镜研究了大型共聚物膜产品的表面形貌和形貌。
