Investigation of Room Temperature Ionic Liquids as Environmentally Benign Solvents for Free Radical Polymerization

吉米·W·梅斯研究所：阿拉巴马大学伯明翰分校建议编号：0086874室温离子液体(RTIL)正在成为环境危险的挥发性有机化合物溶剂(VOC)的替代品，传统上用作工业溶剂。RTIL提供了一种溶解介质，许多有机和无机化合物可以在其中溶解。它们不挥发，不易燃，具有很高的热稳定性，而且制造成本低，容易制造。聚合物工业是化学工业的主要组成部分，VOCs在聚合以及聚合物分离和提纯过程中用作溶剂。在聚合物生产中，用RTILs代替VOCs可使该行业受益。本项目将研究RTILs中导电性自由基加成聚合的可行性。这将是一名聚合物化学家、一名无机化学家和一名化学/聚合物工程师之间的合作研究。该小组还将与工业合作伙伴合作，评估一些不同的RTIL以及不同的乙烯基和丙烯酸单体。将特别强调开发在整个聚合物合成和分离过程中完全避免使用VOCs的工艺。除了常规的自由基聚合，还将研究RTIL中的活性自由基聚合。这些活性聚合工艺提供了生产定制聚合物和共聚体系结构并限制多分散性的潜力，同时避免了与离子聚合工艺相关的高成本。还将为所使用的RTILs生成基本工程和毒性日期。

ABSTRACTPI: Jimmy W. Mays Institution: University of Alabama at BirminghamProposal Number: 0086874Room temperature ionic liquids (RTILs) are emerging as replacements for environmentally dangerous volatile organic compound solvents (VOCs) traditionally used as industrial solvents. RTILs offer a solvating medium in which a number of organic and inorganic compounds can be dissolved. They are non-volatile, non-flammable, have high thermal stabilities, and are inexpensively and easily manufactured. The polymer industry is a major segment of the chemical industry and VOCs are used as solvents in polymerization as well as polymer isolation and purification processes. This industry could benefit by replacing VOCs with RTILs in polymer production.This project will be a study of the feasibility of conduction free radical addition polymerizations in RTILs. It will be a collaborative study between a polymer chemist, an inorganic chemist and a chemical/polymer engineer. The group, also working with industrial collaborators, will evaluate a number of different RTILs and different vinyl and acrylic monomers. Special emphasis will be placed on developing processes that completely avoid the use of VOCs throughout the polymer synthesis and isolation process. In addition to conventional free radical polymerization, living free radical polymerization in RTILs will also be studied. These living polymerization processes offer the potential to produce tailored polymer and copolymer architectures and limit polydispersity, while avoiding the high cost associated with ionic polymerization processes. Fundamental engineering and toxicity date will also be generated for the RTILs used.
