NSF Support for Travel Expenses for US Participants in ACS Symposium "Controlled Living Radical Polymerization" to be held in Denver, CO August 28-31, 2011

合成和表征具有精确控制的大分子尺寸、官能团和组成以及明确定义的拓扑结构的新材料是当代聚合物科学的终极目标。多年来，自由基聚合中的分子结构和官能度的控制一直是非常困难的。然而，最近的可控/活性聚合已经扩展到自由基体系，这些体系不仅在商业上是最重要的，而且由于可聚合单体的可获得性、容易的共聚和不要求的反应条件而具有最大的潜力。因此，乙烯基单体的可控/活性自由基聚合扩展和增强了基础知识。该提案请求支持3名美国助理教授、3名博士后研究员和3名研究生参加2011年8月28日至31日在科罗拉多州丹佛市举行的美国化学学会全国会议上举行的“受控/活性自由基聚合”研讨会。研讨会将讨论受控/生活系统的最新进展。重点介绍了控制自由基聚合的三种一般方法。这包括使用氮氧化物和其他有机稳定的自由基，金属催化聚合的应用，如原子转移自由基聚合，以及使用链转移和加成-裂解化学的技术，包括异构体。这些讲座将涉及具有新的分子结构、功能和组成的材料的机理、合成和表征。研讨会将包括一次辅导和7次常规会议，约80次讲座和6次海报会议。会议将允许各国研究人员和许多美国学术界(包括研究生和博士后)、政府和工业实验室交流和传播信息。非技术摘要可控自由基聚合是聚合物和材料科学发展最快的领域之一。它影响了许多先进技术，使生物医学材料、光电子学、环境相关领域以及其他领域，如涂料、润滑剂、粘合剂、添加剂、表面活性剂、分散剂以及保健和美容产品取得了前所未有的进步。因此，2011年丹佛“受控/活性自由基聚合”研讨会期间产生的知识将使许多与会者受益，包括本科生和研究生、博士后研究员、他们的导师以及来自政府和工业实验室的研究人员。与2008年在费城举行的关于“受控/活性自由基聚合”的美国计算机协会研讨会的情况一样，国际和平协会计划发布会议记录和会议上的主要演讲。

TECHNICAL ABSTRACTSynthesis and characterization of new materials with precisely controlled macromolecular dimensions, functionalities and composition as well as with well-defined topologies is the ultimate goal of contemporary polymer science. For many years control of molecular architecture and functionalities in radical polymerization was very difficult. However, recently controlled/living polymerizations have been extended to radical systems which are not only commercially the most important but also have the largest potential due to availability of polymerizable monomers, facile copolymerization and undemanding reaction conditions. Therefore, controlled/living radical polymerization of vinyl monomers expands and enhances fundamental knowledge. This proposal requests support for 3 US assistant professors, 3 postdoctoral fellows and 3 graduate students to participate in the Symposium on "Controlled/Living Radical Polymerization" at the National Meeting of the American Chemical Society in Denver, CO, August 28-31, 2011. The Symposium will cover recent advances in controlled/living systems. Three general approaches to controlled radical polymerization will be highlighted. This includes use of nitroxides and other organic stable radicals, application of metal catalyzed polymerization such as atom transfer radical polymerization, and techniques employing chain transfer and addition-fragmentation chemistry, including inifers. The lectures will cover mechanisms, synthesis and characterization of materials with novel molecular architectures, functionalitiesand composition. The symposium will include one tutorial and 7 regular sessions with approximately eighty lectures and 6 poster sessions. The meeting will allow to exchange and disseminate information among researchers from various countries and many US academic (including graduate students and postdoctoral fellows), governmental and industrial laboratories.NON-TECHNICAL ABSTRACTControlled radical polymerization is among the most rapidly developing areas of polymer and materials science. It impacts many advanced technologies enabling unprecedented advances in biomedical materials, optoelectronics, environmentally related areas and other areas such as coatings, lubricants, adhesives, additives, surfactants, dispersants and health and beauty products. Thus, knowledge generated during the 2011 Denver Symposium on "Controlled/Living Radical Polymerization" will benefit many participants, including undergraduate and graduate students, postdoctoral fellows, their advisors as well researchers from governmental and industrial laboratories. As in the case of the previous 2008 ACS Symposium on "Controlled/Living Radical Polymerization" held in Philadelphia, the PI plans to publish proceedings with the major lectures presented at the meeting.
