Herein we show the formation of a polymer stereocomplex by mixing isotactic, regioregular chains of poly(propylene succinate) synthesized via the copolymerization of cyclic anhydrides and epoxides. The stereocomplex exhibits significantly improved thermal properties in comparison to the enantiopure parent polymers. We demonstrate that stereocomplexation is a route to a new class of semicrystalline polyesters with improved properties, produced from readily accessible starting materials.
本文通过环状酸酐和环氧化物共聚合成的等规、区域规整聚（琥珀酸丙二醇酯）链的混合，展示了聚合物立构络合物的形成。与手性纯的母体聚合物相比，该立构络合物表现出显著改善的热性能。我们证明了立构络合是一种制备具有改善性能的新型半结晶聚酯的途径，这些聚酯由易得的起始材料制成。
