摘要
采用自由基共聚合反应制备了具有不同侧链聚合度、不同分子量、不同反应温度和不同羧基/侧链比的共聚羧酸类超塑化剂,并对其减水率、坍落度保持能力、凝结时间、引气能力和抗压强度进行了试验研究,进而得知各个结构特征对以上性能的影响规律。
The free radical co-polymerization reaction was applied to synthesize a serials ofpoly carboxylate（ PC ） superplasticizer with different properties, such as different polymerization degree of graft chain, different molecular weight, different temperature and different carboxyl/graft chain.And all of the superplasticizers synthesized were evaluated systematically through the items,such as water reducing effect, slump loss, setting time, air entraining ability and compressive strength, by which principles influencing PC performance were obtained.And this may provide instructive advice for application of PC.
