Objective of this study is to elucidate order and responsiveness in the disordered materials, which are unique characteristics of polymeric materials, Namely, we tried to understand structures and dynamics of soft-materials through controlling the structural disorder and analyzing their functions. We discussed on the results of our respective researches with each other, in personal and/or group meetings, by setting the following more detailed subjects : (1) Conformation and dynamics of isolated polymer molecules (2) Changes in structure and properties of dilute-, semidilute-solutin and bulk polymers with change of concentration as a function of molecular characteristics (3) Physical properties of polymer blends and block copolymers (4) Theoretical considerations on these problems from phenomenological and molecular points of view. The results of the studies and discussion were presented in the two meeting held in Jan.of 1996 and Jan.1997, where all members of the research group and some invited speakers got together, discussed and exchanged scientific information. Contents of the presented results in the meetings were summarized in two booklets with each having 129 and 247 pagers, respectively.

本研究的目的是阐明无序材料中的有序性和响应性，这是聚合物材料的独特特性，即我们试图通过控制结构无序和分析它们的功能来理解软材料的结构和动力学。我们在个人和/或小组会议上讨论了各自的研究结果，确定了以下更详细的主题：（1）孤立聚合物分子的构象和动力学（2）稀、稀聚合物分子结构和性质的变化浓度随分子特性变化的半稀溶液和本体聚合物（3）聚合物共混物和嵌段共聚物的物理性质（4）从唯象和分子观点对这些问题的理论思考。1996年1月和1997年1月举行的两次会议上，研究小组的所有成员和一些应邀发言者聚集在一起，讨论和交流科学信息。在会议上介绍的结果的内容总结在两本小册子中，每本小册子分别有129页和247页。
