Abstract

In this paper, using maleic anhydride (MA), allyl polyethylene glycol (AP), methyl allyl sulfonate (SM) as monomer and ammonia persulfate (KPA) as initiator, a polyether high-performance water-reducing agent for polyglycolic acid (PR) on good compatibility in sulphoaluminate cement (SAC) was synthesized by solution polymerization and orthogonal design. And the effects of various factors (reaction time, branched length and density of PR etc.) on the performance of PR were also studied. Results show that the optimum formula was as follows: the polymerization degree of AP was 56, the mass molar ratio of three monomers was n (MA): n (AP): n (SM) = 3:2:1, the amount of AP accounted for 9% of the total molar content of monomer, the reaction temperature was 65 °C, and the reaction time was 5 h.

聚乙醇酸高性能减水剂的合成与合成

摘要

本文以马来酸酐(MA)、烯丙基聚乙二醇(AP)、烯丙基磺酸甲酯(SM)为单体,过硫酸氨(KPA)为引发剂,制备了聚乙醇酸(PR)的聚醚高性能减水剂通过溶液聚合和正交设计合成了在硫铝酸盐水泥(SAC)中具有良好相容性。并研究了各种因素(反应时间、支化长度和PR的密度等)对PR性能的影响。结果表明,最佳配方为:AP的聚合度为56,三种单体的质量摩尔比为n(MA):n(AP):n(SM)=3:2:1,用量为AP占单体总摩尔含量的9%,反应温度65℃,反应时间5h。
