U.S.-Korea Cooperative Research: A Fundamental Study on Polyurethane-Unsaturated Polyester Interpenetrating Network

该提案要求提供资金，以允许理工大学化学工程系的Chang Dae Han博士与韩国科学技术高级研究所的Sung Chul Kim博士在24个月的时间内开展一项关于聚酯-不饱和聚酯互穿网络基本方面的合作研究计划。具体而言，合作者将开发（1）用于描述聚乙烯-不饱和聚酯共混物固化反应的动力学模型，（2）用于描述这些共混物在固化过程中粘度变化的化学流变学模型，以及（3）用于模拟此类共混物制浆过程的数学模型。通过建立一个坚实的基础，了解聚氨酯-不饱和聚酯共混物的固化反应，并确定最佳的加工条件，以产生所需的最终用途的性能，研究人员试图能够开发新的树脂或修改现有的树脂，为特定的应用，并更好地控制加工操作。虽然拟议的合作项目是一个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产生重要影响。这两位合作者是备受尊敬的科学家，他们长期从事聚合物系统的平行研究。本项目将使他们能够联合收割机在重要和有趣的研究中结合其互补的才能和经验。该项目与美国的目标有关-韩国合作科学计划，旨在通过科学信息，思想，技能和技术的交流以及通过互利问题的合作来提高美国和韩国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层面，该研究由美国国家科学基金会资助，资助号为MSM 8744680。

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.
