The product is an important raw material for polycarboxylate superplasticizer which is formed by the macro-monomer copolymerize with acrylic acid. The hydrophilic group in the synthesized copolymer(PCE) can improve the hydrophily the dispersibility of the copolymer in water. The synthesized copolymer(PCE) has good dispersibility, high water reducing rate, good slump retention, good enhancing effect and duribility, also is environmentally friendly and widely used in premix and cast-in concrete.


Characteristics

♦High active catalyst&special synthesis technical process
