摘要

传统石油基塑料难以降解，带来了严峻的环境污染，已成为全球性的社会热点问题. 近期洪缪课题组通过巧妙的单体设计与催化系统开发，创新性地发展了一种异构化驱动不可逆开环聚合的新策略，实现了非张力环单体在工业条件下的高效聚合，为将“挑战性”五元环内酯高产率转化成性能优越的可持续性含硫高分子材料提供了新途径.

Abstract

The non-degradable nature of petroleum-derived plastics causes serious environmental pollution

which has become a global public crisis. Hong and co-workers develop an effective and robust strategy utilizing isomerization-driven irreversible ring-opening polymerization (IROP) for converting "non-strained" five-membered

-thionobutyrolactone into poly(

-thionobutyrolactone) (PTBL). The IROP can be conducted at industrially relevant temperature of 80-100 ℃ and afford PTBL with high molecular weight

which is commonly inaccessible by the other polymerization methods. Different from most conventional ring-opening polymerizations

this IROP approach is thermodynamically driven by the S/O isomerization rather than the ring strain. PTBL can be easily degraded into non-strained

-butyrothiolactone with added value

thus establishing a sustainable model for polymer recycling. PTBL exhibits a wide range of notable properties resembling commercial low density polyethylene

making it promising for many potential applications.
