The Application and Synthesis of Dipolyethylene Glycol Maleate

Abstract:

Dipolyethylene glycol maleate was synthesized by decompression melting method, and the synthetic process was discussed. Five factors were optimized, including alcohol acid mole ratio, amount of catalyst, inhibitor dosage, reaction temperature and reaction time, designing L₁₆(4⁵) for orthogonal experiment. The best condition was determined: alcohol acid mole ratio is 2.1:1, the amount of catalyst is 4%,the inhibitor dosage is 3%, the reaction temperature is 120°C and the reaction time is 6h, the esterification rate reaches 96.46%. The macromonomer copolymerized with sodium allylsulfonate to produce polycarboxylate superplasticizer. The water consumption of Lithium ion battery slurry reduces 27% when the superplasticizer dosage is 0.6%. Slurry viscosity is 1786.6 MPa.s and 2680.3 MPa.s after 90min which meet requirements for coating technology.
