摘要
用水溶液调聚的方法合成出低聚型二元共聚物，考察了聚合时间、引发剂用量、单体配比等因素对反应的影响。研究结果表明：该二元共聚物可作为控制坍落度损失的高效减水剂。
To solve the problem of concrete slump decreas the syntnesis of a new type copolymer was studied and the optimum reaction conditions were determined. The experimehtal results indicated that the new type copolymer would be optirnum high efficient water reducer.
