Aluminum complexes have appropriate binding affinity with sulfide propagating species, avoiding catalyst poisoning and minimizing epimerization reactions. By proper ligand design and modification, the aluminum catalysts enabled the production of highly isotactic, stereocomplexed polythioester. The obtained dithiolactone-based plastic is a tough semicrystalline material, and exhibits complete recyclability
铝络合物与硫化物增长物质具有适当的结合亲和力,可避免催化剂中毒并最大限度地减少差向异构化反应。通过适当的配体设计和修饰,铝催化剂能够生产高度全同立构的立体络合聚硫酯。获得的二硫内酯基塑料是一种坚韧的半结晶材料,具有完全的可回收性。
