The objective of this proposal is to understand and consequently to control the mechanism of carbocationic polymerizations, and thus to develop useful new materials and processes of readily available monomers and equipment, respectively. This overall objective embraces six major specific (and numerous subordinate) objectives: 1) To explore the fundamentals of recently discovered living carbocationic polymerizations; 2) To expand the scope of such systems; 3) To exploit seed experiments for copolymers; 5) Macromers; and 6) To combine cationic with living anionic polymerization for the synthesis of other hitherto unavailable materials. The methodologies toward these objectives are partly in place (conventional techniques in combination with new techniques) and partly will be developed. This research is significant for the creation of basic knowledge which is, however, exploitable for the preparation of new specialty materials with a combination of unique properties and for new multipurpose polymerization processes. The possibilities include: New amphiphilic networks for biomaterials for artificial organs and controlled drug delivery, new macromers for engineering applications, new coatings, new diblocks for blending, etc.

这项建议的目的是了解并控制碳阳离子聚合的机理，从而开发出有用的新材料和新工艺，分别用于现成的单体和设备。这一总体目标包括六个主要的具体(和众多从属)目标：1)探索最近发现的活性碳阳离子聚合的基本原理；2)扩大这类体系的范围；3)开发共聚物的种子实验；5)大单体；以及6)将阳离子与活性阴离子聚合相结合，以合成其他迄今尚未获得的材料。实现这些目标的方法论部分已经到位(传统技术与新技术相结合)，部分将被开发。这项研究对于创造基础知识具有重要意义，然而，这些基础知识可用于制备具有独特性能的新特种材料和新的多用途聚合工艺。可能性包括：用于人工器官和受控药物输送的生物材料的新的两亲性网络，用于工程应用的新的大分子单体，新的涂层，用于混合的新的双嵌段等。
