Manufacturing of resins and rubbers, as well as their products, is an important industrial sector in Canada with over thirty billion annual shipments. Volume consumption of polymers is more than all other types of synthetic materials combined. Polymers are chain molecules and their properties are determined to a large extent by chain microstructure such as molecular weight, composition, branching, network, etc. Improving product quality by designing chain microstructure has been a great challenge for polymer researchers. Recent development in living radical polymerization (LRP) chemistry provides excellent opportunities. In LRP it takes several hours for individual polymer chains to fully grow, while in conventional radical polymerization it is in seconds from initiation to termination. The extended time duration makes it possible for polymer reaction engineers to design and control chain microstructure.

树脂和橡胶及其产品的制造是加拿大重要的工业部门，年出货量超过300亿。聚合物的体积消耗量超过所有其他类型合成材料的总和。聚合物是链状分子，其性能在很大程度上取决于分子量、组成、支化、网络等链状微观结构，通过设计链状微观结构来提高产品质量一直是聚合物研究者面临的巨大挑战。活性自由基聚合（LRP）化学的最新发展提供了极好的机会。在LRP中，单个聚合物链完全生长需要几个小时，而在传统的自由基聚合中，从引发到终止只需几秒钟。延长的持续时间使得聚合物反应工程师能够设计和控制链微观结构。
