The overall objective of this grant is the preparation of unique novel, potentially useful, polymeric materials by new syntheses employing inexpensive monomers/chemicals and conventional equipment. The synthesis methods involve living carbocationic polymerizations (LC+Pzn) or a combination of LC+Pzn with other techniques, and are based on recently generated mechanistic insight . While the emphasis is always on synthesis, the elucidation of structure/property relationships and a measure of mechanical testing to suggest utility are essential parts of the projects. The proposal consists of four main projects and numerous subordinate projects: 1. Living Cationic Azeotropic Copolymerization of Isobutylene and Styrene, and Isobutylene/Styrene Copolymers Prepared by this Route. 2. Organic/Inorganic Hybrid Stars and Networks by Sol/Gel Chemistry. 3. New Thermoplastic Elastomers by Combination of Living Cationic and Radical Polymerizations. 4. Synthesis and Characterization of Novel Amphiphilic Membranes (two subprojects): A. Chemically Crosslinked Membranes, and B. Physically Crosslinked Membranes.These projects concern the preparation of novel prototype materials and investigations suggesting utility for various engineering and biomaterials applications; therefore the potential impact on advancing knowledge in designed polymeric materials could be significant. The projects will be carried out by graduate students in polymer science.

该赠款的总体目的是通过采用廉价的单体/化学物质和常规设备的新合成来制备独特的新型，潜在有用的聚合物材料。 合成方法涉及活碳质聚合（LC+PZN）或LC+PZN与其他技术的组合，并基于最近生成的机械洞察力。 虽然重点始终是综合，但结构/财产关系的阐明以及机械测试的度量表明效用是项目的重要组成部分。 该提案由四个主要项目和众多下属项目组成：1。异丁烯和苯乙烯的活阳离子共聚物共聚，以及该路线编制的异丁烯/苯乙烯/苯乙烯共聚物。 2。溶胶/凝胶化学的有机/无机杂交星和网络。 3。通过生物阳离子和根治性聚合的组合，新的热塑性弹性体。 4。新型两亲性膜的合成和表征（两个亚物体）：A。化学交联的膜和B.物理交联的膜。这些项目涉及新型原型材料的准备，并提示用于各种工程和生物材料应用的实用性；因此，对设计的聚合物材料中的知识的潜在影响可能很大。 这些项目将由聚合物科学的研究生进行。
