摘要：
A series of comb-shaped copoiymers of polycarboxylic acid type were synthesised by copolymerizing polyoxyethylene allyl methyl diether (APEO-n), maleic anhydride (MAn), and/or styrene (St). The effects of structure and composition of copolymers on dispersing capability were studied. The results showed that the properties of superplastisizer were affected by the length and density of graft chain. The superplasticizer has excellent dispersing capability as the length of graft chain is 20-60, and the St is 5%-20% (mol).
