Description
Summary:Vinyl polyoxyethylene ether type polycarboxylate superplasticizer PCE-6C is prepared by copolymerization of vinyl polyoxyethylene ether and acrylic acid. The initiation system is a hydrogen peroxide-sodium formaldehyde sulfoxylate hydrate redox initiation system. The chain transfer agent is mercaptopropionic acid. The test results show that the monomer conversion rate of the synthesized PCE-6C is high and the dosage sensitivity of PCE-6C is significantly better than that of the conventional ester type polycarboxylate superplasticizer and the conventional ether type polycarboxylate superplasticizer, and the water consumption sensitivity and temperature sensitivity of PCE-6C is slightly better than that of the conventional ester type polycarboxylate superplasticizer and the conventional ether type polycarboxylate superplasticizer.
