The results showed that the properties of superplastisizer were effected by the end group, the esterification, the length and density of graft chain.
结果表明:超分散剂的性能受端基效应、酯化[作用]用、接枝链的长度和密度的影响,当接枝链长度为30时,分散性能良好。
Selection of catalysts, reaction temperature and the ratio of reactants on the esterification were studied.
报道用Lewis酸催化合成偏苯三酸三 (2 乙基 )已酯结果 ,研究了催化剂的选择与用量、反应物配比以及反应温度对酯化[作用]用的影响 ,确定了最佳合成条
