中文摘要：

氮氧自由基调控聚合（NMP）是制备微观结构可控（如窄分子量分布）的聚合物材料最主要的技术手段之一。在过去的二十年间，NMP取得了相当大的成就，实现了MMA、n-BA、丙烯酰胺，二烯烃和丙烯腈等多种单体的可控／“活性”聚合，分子量分布达到1．1以下，同时利用NMP制备了具有既定结构的聚合物，如嵌段聚合物、接枝聚合物、星形聚合物和梳形聚合物等。而与光聚合技术的结合，使NMP聚合取得了更大的突破，实现了室温下的光可控／“活性”聚合，且大大提升了聚合反应速率；近年来光引发氮氧自由基调控聚合的研究进展主要集中在光敏化技术方面，包括分子内敏化和分子间敏化，本文对其各自的敏化机理和研究成果进行总结和评述，希望有助于国内读者了解这方面研究工作的状况，促进国内相关研究工作的发展。

英文摘要：

Nitroxide-mediated radical polymerization （NMP） is one of the most important techniques to prepare polymer materials with well-defined molecular structure, and made considerable achievements in the past decades, achieving the controlled/living polymerization of kinds of monomers such as MMA, n-BA, acrylamide, alkadiene and acrylonitrile, with PDI-~I. 1~ and succeeding in producing a significant variety of architectures including block copolymers such as graft, star, and comb structure, etc. Moreover, the combination with photo-initiated technique presented NMP a greater breakthrough, performing control/living polymerization in room temperature, which is with more rapid reactive rate. The recent developments of photo- initiated nitroxide-mediated polymerization had focused on the new photosensitive technique, including intermolecular and intramolecular photosensitization. In this paper, we review the recent achievements of photosensitization applied in NMP and give understanding on the photosensitized mechanism, it would be help to research working deeply in this area.
