摘要
通过"分子设计",研制了有不同侧链的聚羧酸共聚物,并用红外光谱对产物结构进行表征,着重讨论了聚乙二醇分子量对水泥分散性能的影响。实验结果表明:通过控制侧链长度,使聚羧酸共聚物具有最佳的分散性能。
A type of co-poly carboxylic acid with different side-chain was synthesized, by using a 'purpose building'. The product was characterized and analyzed by FT-IR. Influence of molecular weights of PEG on dispersing property on cement was discussed. The results showed that a type of co-poly carboxylic acid with better dispersion can be synthesized by the way of change of dimension of the side-chain.
