Specific Interactions in Polymer Systems

9525924画家在未来三年内，我们会致力推行三个主要范畴。(1)链连接影响。这是一个重要的课题，我们建议对链连接性的影响进行系统的研究，这可以通过对低分子类似物、聚合物溶液、无规共聚物和氢键的聚合物共混物的系统研究来实验测量。(2)可混溶聚合物添加剂的设计。继我们成功设计了一种用于聚四氢呋喃的聚合物抗氧剂后，我们建议将我们的理论概念和实验研究扩展到高分子添加剂的设计、合成和研究。(3)多个相互作用的部位。我们可以通过在同一条链上加入不同类型的氢键官能团(即多个相互作用位点)来控制有利和不利相互作用的平衡。我们建议对这些因素进行系统的探索。%这项研究将在不同聚合物材料之间的兼容性和相互作用的广泛领域提供新的知识，这对加工、回收和环境问题具有影响。***

9525924 Painter There are three major thrust areas that will be pursued during the next three years. (1) Chain Connectivity Affects. This is an important topic and we propose to perform a systematic study of chain connectivity affects which can be measured experimentally by methodical studies of low molecular analogues, polymer solutions, random copolymers and polymer blends that hydrogen bond. (2) Design of Miscible Polymeric Additives. Following our successful design of a polymeric antioxidant for polytetrahydrofuran we propose to extend our theoretical concepts and experimental studies to the design, synthesis and study of macromolecular additives. (3) Multiple Interacting Sites. We can control the balance of favorable and unfavorable interactions by incoporating different types of hydrogen bonding functional groups in the same chain (i.e. multiple interacting sites). We propose to systematically explore these factors. %%% This study will provide new knowledge in the broad area of compatibility and interactions between dissimilar polymeric materials, which has implications on processing, recycling, and environmental issues. ***
