By grafting a number ofmonomers such as acrylic acid,acrylamide, hydroxyethyl acrylate,methyl acrylate,ethyl acrylate, butyl acrylate, methyl methacrylate, butyl methacrylate, vinyl acetate and acrylonitrileonto granular corn starch respectively and then combinatively, the influence of the graftmonomers upon the sizing properties of starch graft copolymers was studied, and the sizingproperties was improved markedly. The experiments demonstrate that the graft monomershave a marked influence upon the sizing properties and a variety of graft comonomers can improve the sizing properties of starch graft copolymer dramastically. 变性淀粉 接枝共聚 淀粉接枝共聚物 浆料 单体 上浆性能 modified starch graft copolymerization starch graft copolymer warp sizes monomer sizing properties TQ432.2 国家教委博士学科点专项科研基金 1995-04-01 2021-04-01 4
