| Abstract: | 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. |
