Tóm tắt

 It remains a long-standing challenge for chemical recycling of polyhydroxyalkanoates (PHAs) to propiolactone-based monomers due to the high ring strain and many inevitable side reactions. In this contribution, a novel α-spiro-cyclohexyl-propiolactone (SHPL) has been designed with high reactivity toward ring-opening polymerization even at a catalyst loading of <
 1 ppm. The resulting poly(3-hydroxy-2-spiro-cyclohexylpropionate) (P3HSHP) exhibited high thermal stability with a
