Abstract:Global demand for polymeric materials is high and rapidly increasing, with production growing by 40 % over the past decade. It is essential to find alternatives to petrochemical feedstocks; carbon dioxide (CO2) is an ideal substitute as it is cheap, non-toxic, abundant and a waste product ofindustrial processes. The ring-opening copolymerisation (ROCOP) of CO2 and epoxides has enabled access to novel and industrially relevant polycarbonate materials but is largely limited by the epoxide monomer. While the ROCOP of epoxides with CO2 to form polycarbonates is well-established, the use of alternative monomers to form polyurethanes from CO2 remains underexplored and offers apotentially transformative route towards original sustainable materials. This proposal aims to develop catalytic routes towards novel functionalised polyurethanes and polyurethane derivatives, to develop a series of new materials with potential applications as high-performance coatings.This will be delivered through three key work packages, involving:1) Catalyst Screening (to build up mechanistic understanding);2) Catalyst Development (to synthesise the next generation of catalysts);3) Synthesising a Range of Novel Polyurethanes (to create a suite of new polymeric materials with broad-ranging properties).Successful project delivery will generate new methodologies for producing polyurethanes, which avoid the use of diisocyanates (a class of chemicals currently used in the industrial preparation of polyurethanes that are highly toxic and will soon be banned in several EU countries). Thisproject will also provide a new method of upcycling CO2 into value-added products.

摘要：全球对聚合物材料的需求很高且迅速增加，在过去的十年中，产量增长了40％。找到石化原料的替代品是至关重要的。二氧化碳（CO2）是理想的替代品，因为它便宜，无毒，丰富和工业工艺的废物。二氧化碳和环氧化物的共聚物共聚（ROCOP）已使新型和工业相关的聚碳酸酯材料获得了访问，但在很大程度上受环氧化物单体的限制。虽然具有二氧化碳的环氧化物rocop以形成聚碳酸酯，但使用替代单体从二氧化碳中形成聚氨酸盐的使用仍未得到充分兴奋，并为原始的可持续材料提供了基本变化的途径。 This proposal aims to develop catalytic routes towards novel functionalised polyurethanes and polyurethane derivatives, to develop a series of new materials with potential applications as high-performance coatings.This will be delivered through three key work packages, involving:1) Catalyst Screening (to build up mechanistic understanding);2) Catalyst Development (to synthesise the next generation of catalysts);3) Synthesising a Range of Novel聚氨酯（创建具有广泛特性的新的聚合物材料）。成功的项目交付将生成生产聚氨酯的新方法，避免使用二异氰酸酯（目前在工业制备中使用的一类化学物质，这些化学物质是强大的毒性，并且很快将在几个Euu necranded中使用）。该项目还将提供一种将CO2升级为增值产品的新方法。
