Effects of polycarboxylate superplasticizer equipped with β
Then β-P was employed to synthesize a polycarboxylate superplasticizer with β-CD grafted on the side chain [PAA-g-(β-P) n HPEG]. The functional groups, molecular weights, and molecular weight distributions of synthesized copolymers PAA-g-(β-P) n HPEG were characterized by Fourier transform infrared spectra (FT-IR), 1 H nuclear magnetic

Therefore, the synthesis of early-strength polycarboxylate superplasticizer agent has better early strength performance and mass ratio of process conditions. To: HPEG-5000: AA: DAC: thioglycolic acid = 175.00: 13: 1.96: 0.75. Based on the molecular structure design and research of the above polycarboxylate superplasticizer,
Study on the synthesis and properties of benzoate modified
Then, BA-HPEG and HPEG were copolymerized with acrylic acid (AA) with an alkyd ratio of 2:1 to obtain three novel polycarboxylate superplasticizer BA-PCE-10, BA-PCE-20 and BA-PCE-30 with good flow retaining behaviors of cement mortars.
Synthesis of polycarboxylic ether superplasticizers based on
In the production of polycarboxylate superplasticizer, the amount of residual monomer is an important factor to influence product quality. In order to determine the content of different monomers in superplasticizer, the residual monomers in macromolecular materials can be determined by HPLC.
