  The invention discloses a class of new polymers, trans-ring-fused poly(4-hydroxybutyrate)s (RF-P4HB) that exhibit a unique set of properties, including robust thermal stability and mechanical strength, quantitative recyclability to the building block monomers via thermolysis and/or chemical catalysis, and convenient production from the chemical ring-opening polymerization under ambient temperature and pressure. Another unique property is the formation of crystalline stereocomplexed polymers with high melting temperature upon mixing the two enantiomeric RF-P4HB chains via stereocomplexing co-crystallization. This invention also provides the corresponding ring-fused lactone monomer structures that enable the synthesis of the RF-P4HB polymers, through trans-fusing of rings to the parent γ-butyrolactone ring. Furthermore, a polymerization or copolymerization process for the synthesis of RF-P4HB polymers and copolymers is disclosed.

  本发明揭示了一类新型聚合物，即转环融合的聚(4-羟基丁酸酯) (RF-P4HB)，具有一系列独特性质，包括优良的热稳定性和机械强度，通过热解和/或化学催化定量回收为构建单体的便利性，以及在常温常压下通过化学环开聚合方便地生产。另一个独特性质是通过立体共结晶协同结晶混合两个对映异构体 RF-P4HB 链形成具有高熔点的结晶立体复合聚合物。该发明还提供了相应的环融合内酯单体结构，可通过将环转移至母体 γ-丁内酯环来合成 RF-P4HB 聚合物。此外，还揭示了一种用于合成 RF-P4HB 聚合物和共聚物的聚合或共聚过程。
