The Structure and Composition Analysis, Synthetic Design and Performance Research of Unknown Polycarboxylate Superplasticizer

In this paper, the unknown polycarboxylate superplasticizer was separated and purified by ultrafilatration technology. Some instrumental analysis method were used in order to research the structure and composition such as IR, NMR, LC, GC, GPC. According to the analysis results, the synthetic polycarboxylate superplasticizer was obtained by free radical polymerization through orthogonal experiment. Comparing by the structure and performance of the unknown and the synthetic sample, it could confirm that using the monitoring and tracking analysis technology on the latest research and development of new product can provide accurate information of science and technology and market information.
