报告题目：Macromolecular Engineering Enabled by ATRP
Various advanced nanostructured functional materials were recently designed and prepared by controlled/ living radical polymerization (CRP). More than 100 million tons of polymers are produced annually world-wide by conventional radical polymerization. However, macromolecular engineering is impossible in this process. Copper-based ATRP (atom transfer radical polymerization) catalytic systems are among most efficient CRP systems.Recently, Cu level in ATRP was reduced to a few ppm by applying new initiating/catalytic systems which are 1 billion times more active than original catalysts. ATRP of acrylates, methacrylates, styrenes, acrylamides, acrylonitrile and other vinyl monomers was employed for macromolecular engineering of polymers with precisely controlled molecular weights, low dispersities, designed shape, composition and functionality. Examples of block, graft, star, hyperbranched, gradient and periodic copolymers, molecular brushes and various hybrid materials and bioconjugates prepared with high precision will be presented. These polymers can be used as components of various advanced materials such as health and beauty products, biomedical and electronic materials, coatings, elastomers, adhesives, surfactants, dispersants, lubricants, additives, or sealants.
Krzysztof Matyjaszewski，卡耐基梅隆大学著名教授，是世界知名的高分子化学家，因其发现与普及原子转移自由基聚合而闻名于世。这一新的聚合方法彻底革新了高分子的合成方式，成为当今高分子研究的主流方向之一。他关于ATRP聚合的首篇论文(Journal of the American Chemical Society, 1995)与首篇综述(Chemical Reviews 2001)已被引用超过9000次。他是多个重要国际化学和高分子学会和组织的主席/负责人，是美国国家工程院院士、波兰科学院、俄罗斯科学院外籍院士，曾任亚太高分子学会主席。同时，他还积极推广原子转移自由基聚合的工业化进程，超过56个公司成为他主办的ATRP/CRP联合会会员，如今已许可了16项产品的生产。
