Radical polymerisation is the most commercially important polymer process, favoured by industry for its broad scope and relatively low cost and environmental impact. However, its use in the synthesis of 'smart materials' for biomedical applications, molecular electronics and high-performance engineering applications has been hampered by the lack of microstructural control. This project aims to use a complementary combination of theory and experiment to develop novel structured Lewis acids for controlling the stereochemistry in free-radical polymerisation, and to utilise the recently discovered propagation catalysis conferred by simple Lewis acids to minimise defect structures and thereby improve the thermal and photostability of polymers.

自由基聚合是商业上最重要的聚合物工艺，因其范围广、成本和环境影响相对较低而受到工业界的青睐。然而，由于缺乏微观结构控制，其在生物医学应用、分子电子学和高性能工程应用的“智能材料”合成中的应用受到了阻碍。该项目旨在利用理论和实验的互补结合来开发新型结构的路易斯酸来控制自由基聚合中的立体化学，并利用最近发现的简单路易斯酸赋予的传播催化作用来最大限度地减少缺陷结构，从而提高聚合物的热稳定性和光稳定性。
