polycarbonate polyol - an overview | sciencedirect topics
Polycarbonates (PCs) are a type of polymer with carbonate group (-O-CO 2 R-) repeat units within their main backbone and for which CO 2 can be used as building block for their synthesis (44).
ultra-productive upcycling co2 into polycarbonate polyols via borinane ...We herein report the synthesis of commercially attractive low molar mass polycarbonate polyols obtained through the ring-opening copolymerization of CO 2 and epoxides, using a series of borinane-based bifunctional organocatalysts in the presence of chain transfer agents (CTAs).

co2 derived biodegradable polycarbonates: synthesis, modification and ...PPC production base in Tianguan Group. From the standpoint of economy and ecology, it's highly desirable to utilize CO 2 instead of disposing it. One of the cost-effective utilization approaches is to employ CO 2 to produce a series of polymers with biodegradable and tailored properties.
carbon dioxide-based functional polycarbonates: metal catalyzed ...Polycarbonates (PCs) are a class of thermoplastic polymers containing carbonate units in their chemical structure. The most common type of polycarbonates on the market is bisphenol A (BPA) polycarbonate. It is an aromatic polycarbonate with a high glass transition temperature ( Tg) of 140–155 °C.
synthesis and application of co 2 -based polycarbonate polyols and ...<p indent="0mm">The copolymerization of carbon dioxide and epoxides is utilized to synthesize carbon dioxide-based polycarbonate polyols, which are used to prepare carbon dioxide-based polyurethane materials. This approach is becoming an integral part of green polymer chemistry. It is also at the forefront of the national carbon neutrality strategy. This review primarily focuses on the ...
ultra-productive upcycling co2 into polycarbonate polyols via borinane ...One of the most industrially valuable products accessible by copolymerization of CO2 with epoxides is low molar mass, hydroxyl end-capped polycarbonate polyols that served as precursors for the synthesis of polyurethane.38 To enable the preparation of such CO2-based polyols, the copolymerization of CO2with epoxides is generally carried out in th...
