[9422885] Mathias这个项目包括基于多功能丙烯酸酯的单体合成和聚合的基础研究。最近的研究结果表明，在α -甲基位置具有多种悬垂官能团（包括卤化物，醚和特别是酯）的单丙烯酸酯具有控制聚合速率的能力。后者显示出意想不到的快速聚合，这使它们成为通过光聚合快速生成硬薄膜的优秀候选者。与乙醚、碳和胺或酰胺基团连接在α甲基位置的二丙烯酸酯提供了高玻璃化过渡温度材料的入口，这些材料具有从聚合物主链垂坠的多种功能。这些取代基的空间和电子效应对聚合效率和立体化学反应的影响将导致聚合物主链上的5和/或6元环。可以结合的垂坠基团的组合使微光刻，生物和药物用途，催化和超亲核试剂材料以及商业上重要的丙烯酸酯和甲基丙烯酸酯的改性剂的应用成为可能。这个项目包含了新的单体和聚合物，可以极大地改善材料的物理和化学性能。这些材料在光刻和微电子、抗癌和生物材料、表面涂层和封装以及目前使用的丙烯酸酯、甲基丙烯酸酯和斯特苯乙烯材料的性能增强剂方面具有增强的能力。* * *

9422885 Mathias This project encompasses fundamental investigations of monomer synthesis and polymerizations based on multifunctional acrylates. Recent results demonstrate the ability to control rates of polymerization for monoacrylates with a variety of pendant functional groups at the alpha methyl position including halides, ethers and especially esters. The latter display unexpectedly rapid polymerizations which make them excellent candidates for hard and rapidly generated thin films via photopolymerizations. Diacrylates linked at the alpha methyl position with ether, carbon and amine or amide groups provide entry to high glass-transition-temperature materials with multiple functionality pendant from the polymer backbone. The steric and electronic effects of these substituents on the efficiency and stereochemistry of the cyclopolymerization process leading to 5-and/or 6-membered rings in the polymer backbone will be explored. The combination of pendant groups that can be incoprorated makes possible applications in microlithography, biological and drug uses, catalytic and supernculeophilic reagent materials, and modifiers for commercially important acrylates and methacrylates. %%% This project encompasses new monomers and polymers which lead to materials with greatly improved physical and chemical properties. These materials have enhanced capabilities for use in photolithography and microelectronics, anti-cancer and biological materials, surface coatings and encapsulation, and property enhancers for currently used acrylate, methacrylate, and stryrenic materials. ***
