This proposal requests funds to permit Dr. Chang Dae Han, Department of Chemical Engineering, Polytechnic University, to pursue with Dr. Sung Chul Kim, Korea Advanced Institute of Science and Technology, for a period of 24 months, a program of cooperative research on fundamental aspects of the polyurethane-unsaturated polyester interpenetrating network. Specifically, the collaborators will develop (1) kinetic models for describing the curing reactions of polyurethane-unsaturated polyester blends, (2) chemorheological models for describing the variation of the viscosity of these blends during curing, and (3) a mathematical model for simulating the pultrusion process of such blends. By establishing a firm basis for understanding the curing reactions of polyurethane-unsaturated polyester blends and determining the optimal processing conditions for yielding desired end-use properties, the researchers seek to be able to develop new resins or modify existing resins for specific applications and to better control processing operations. Although the proposed cooperative project is basic research on an important polymer blend system, its successful completion could have important implications for the development of new products tailored for specific applications. The two collaborators are highly respected scientists who have long been engaged in parallel studies on polymer systems. The present project will permit them to combine their complimentary talents and experience in important and interesting research. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. The research will add an international cooperative dimension to ongoing research at Polytechnic University supported by the National Science Foundation under Grant No. MSM8744680.

该提案要求资金允许理工大学化学工程系Chang Dae Han博士与韩国科学技术院Sung Chul Kim博士进行为期24个月的合作研究项目，研究聚氨酯-不饱和聚酯互穿网络的基本方面。具体来说，合作者将开发(1)描述聚氨酯-不饱和聚酯共混物固化反应的动力学模型，(2)描述这些共混物在固化过程中粘度变化的化学流变模型，以及(3)模拟此类共混物拉挤过程的数学模型。通过为了解聚氨酯-不饱和聚酯共混物的固化反应建立坚实的基础，并确定获得所需最终用途性能的最佳加工条件，研究人员寻求能够开发新树脂或修改现有树脂以用于特定应用，并更好地控制加工操作。虽然拟议的合作项目是对一种重要的聚合物共混体系的基础研究，但其成功完成可能对开发针对特定应用的新产品具有重要意义。这两位合作者是长期从事聚合物体系平行研究的备受尊敬的科学家。目前的项目将使他们能够在重要而有趣的研究中结合他们互补的才能和经验。该项目与美韩合作科学项目的目标相关，该项目旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作，提高美韩科学家和工程师之间的合作水平。这项研究将为理工大学正在进行的研究增加一个国际合作的维度，该研究得到了美国国家科学基金会（National Science Foundation）的资助。MSM8744680。
