Herein, we describe an effective strategy for synthesizing polythioethers with a well-defined structure through the cationic polymerization of thiirane with electron-withdrawing substituents. This strategy allows for precisely controlling the regio- and stereochemistry of the ring-opening polymerization of 2-phenylthiirane, thus allowing for producing poly(2-phenylthiirane) with high stereoregularity using enantiomeric pure thiirane.

通过阳离子开环聚合制备有规立构聚(2-苯基硫杂丙环)

在此，我们描述了一种通过带有吸电子取代基的硫杂丙环的阳离子聚合来合成具有明确结构的聚硫醚的有效策略。该策略允许精确控制2-苯基硫杂丙环开环聚合的区域化学和立体化学，从而允许使用对映体纯硫杂丙环生产具有高立体规整性的聚(2-苯基硫杂丙环)。
