Study on Esterifying Conditions of Shrinkage Reducing Monomer
Abstract:
One system of Shrinkage reducing monomer was prepared by esterification reaction, the test method of esterification rate was discussed, to find out the significant factors of the esterification rate by using the orthogonal design. The influence of ether-to-acid mole ratio, reaction temperature, catalyst dosage and reaction time on the esterification was also investigated. The results demonstrate that the suitable esterifying conditions mainly require the suitable proportion of MA to C5H12O3 as 1~1.05 to 1, and under the temperature of 120~125°C, and 3~3.5hours of reaction time.
