Carboxylic Groups

A polycarboxylate superplasticizer (PCs) was synthesized by copolymerization of allyl polyoxyethylene ethers (APE), acrylic acid (AA), sodium methylallyl Sulfonate (SMAS) and ethyl acrylate (EA). The effect of functional groups and branch chain on PCs properties was investigated by the test of fluidity of cement paste, retardation performance and Zeta potential of cement particles. The results showed that carboxylic groups and ethyl ester groups can improve water reducing ratio and fluidity of cement paste, and the sulfonic groups has an important contributiion to retardation performance of PCs.

Fourier transform infrared microspectroscopy was applied in order to analyze the interaction of the coated interface between two different polymers. The samples investigated were prepared by coating urethane paint on an ethylene-acrylic acid copolymer (EAA) and on an ethylene-ethyl acrylate copolymer whose ethylester group had been partially hydrolyzed (EAA/EEA). It was demonstrated that a mixed phase was formed along the coated interface between the urethane paint and the EAA and between the paint and the EAA/EEA. The interaction between molecules of the polyurethane and the EAA was observed.
