A new biodegradable CO2-based poly(ester-co-carbonate): Molecular chain building up with crosslinkable domain

Poly(Propylene Carbonate)-Based Biodegradable and Environment-Friendly Materials for Biomedical Applications

“…In addition to biomedical applications, PPC can also be modified for food packing materials [ 7 , 134 ], UV shielding materials [ 135 ], construction materials [ 136 ], agricultural mulching films [ 11 ], degradable surfactants [ 137 ], foaming and blowing materials [ 138 ], solid electrolytes and barriers [ 139 , 140 ] and smart materials [ 104 ] based on its outstanding properties. For a more comprehensive review of PPC in other applications, please refer to previous reviews [ 5 , 85 , 95 ].…”

Sustainable, Recyclable, and Bench-Stable Catalytic System for Synthesis of Poly(ester-b-carbonate)

“…The development of novel catalyst systems, e.g., metal-based catalysts, Lewis pairs, and organocatalysts, has made great strides in the aforementioned designing of sustainable polymers, which are favorable for approaching the synthesis of desirable polymers. ,,− Pioneering work about metal-based catalysts from the groups of Coates, Nozaki, and Williams, amongst others, demonstrated the significant potential of dinuclear catalysts in CO 2 /epoxide ROCOP, the key of these proposed mechanistic hypotheses being that two metal centers at optimum distances could coordinate and catalyze the copolymerization with significantly enhanced activity. ,,,,− Furthermore, we and other groups have reported switchable polymerization, some of which showed better performances in tandem polymerization strategy. ,,,,, In terms of nonmetal catalysts, Li and other researchers reported multiblock poly­(ester- b -carbonate) copolymers through the orthogonal copolymerization of epoxides/CO 2 and ROCOP of CHO/PA with the help of Lewis pairs. − Meanwhile, similar Lewis pair also were reported to successfully synthesize multiblock copolymers by sequential ROCOP of cyclohexene oxide (CHO)/PA and ROP of LLA. , …”
