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～ 6 0、St摩尔分数为 5 %～ 2 0 %时分散性能良好
A series of polycarboxylic acid type comb copolymers were synthesized with polyoxyethylene methylallyl ether (APEO-n), maleic anhydride (MAn) and styrene (St) The results showed that the length and density of graft chains affected the performance of hyperdispersant. When the graft chain length was 20 ~ 60, St mole fraction was 5% ~ 20% dispersion performance is good
