HEC-AM-AMPS共聚物的合成

Synthesis of HEC-AM-AMPS Tercopolymer

用引发聚合方法合成了HEC/AM/AMPS三元共聚物,研究结果表明,在单体总浓度为15%～20%,引发剂浓度0 15%,pH值为中性时,在40～50℃反应8h可以得到转化率为95%,特性粘数12～18dl/g的共聚物。通过红外光谱研究了共聚物分子结构,并通过差热分析研究了共聚物的耐热性。

HECAMAMPS tercopolymer is prepared for EOR in hightemperature and highminerality reservoirs. In this paper, main reaction variables are investigated and tercopolymer of =12～18 dl·g-1 is obtaiined from AM, HEC and AMPS. The molecular structure is identified by IR data.
