摘　　要：以聚氧乙烯甲基烯丙基二醚 (APEO- n)、顺丁烯二酸酐 (MAn)、苯乙烯 (St)等为共聚单体 ,合成了一系列聚羧酸型梳状共聚物 ,研究了共聚物的结构、组成等对分散性能的影响。结果表明 ,接枝链的长度和密度影响超分散剂的性能 ,当接枝链长度为 2 0～ 60、St% (mol% )为 5 %～ 2 0 %时 。A series of comb-shaped copolymers of polycarboxylic acid type with polyoxyethylene allyl methyl diether(APEO-n), maleic anhydride(MAn), and/or styrene(St) were synthesized. The effects of structure and composition of copolymers on dispersing capability were studied. The results show that the properties of superplastisizer are effected by length and density of graft chain. The superplasticizer has excellent dispersing capability as the length of graft chain is 20~60, the content of St is 5 mol%~20 mol%.
