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. ***

9525924油漆工有三个主要的推力领域，将在未来三年内追求。 (1)链连接影响。 这是一个重要的课题，我们建议进行系统的研究链连接的影响，可以通过实验测量的低分子类似物，聚合物溶液，无规共聚物和聚合物共混物，氢键的有条不紊的研究。 (2)可混溶聚合物添加剂的设计。 在我们成功地设计了聚四氢呋喃的高分子抗氧剂之后，我们建议将我们的理论概念和实验研究扩展到大分子添加剂的设计、合成和研究。 (3)多个交互站点。 我们可以通过在同一条链中引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。 我们将系统地研究这些因素。 这项研究将提供新的知识，在广泛的领域的兼容性和不同的聚合物材料之间的相互作用，这对加工，回收和环境问题的影响。 ***
