| 摘 要： | 本文研究了聚氧化乙烯(PEO)和丙烯腈(AN)在水溶液中的超声共聚。共聚速率和AN浓度成正比,存在AN浓度最低限。PEO的降解速率常数越大,它所共聚的AN量越大,表明AN的聚合是由PEO降解生成的大自由基引发生成的。通过元素分析和IR测定证明产物为PEO-AN共聚物。通过POM、TEM、DSC和WAXD测定证实共聚物为结晶嵌段共聚物。

| Abstract: | PEO-AN block copolymers were synthesized in aqueous solution by using ultrasonic technique. The polymerization of AN was initiated by macroradicals produced during ultrasonic degradation of PEO. The rate of reaction was proportional to AN concentration, and the amount of AN copolymerized with per mole of PEO increased with the degradation rate constant of PEO. And the structure of the copolymers was identified by lelementary analysis, IR, POM, TEM, DSC and WAXD. |
