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

该提案要求获得资金，以允许理工大学化工系常大汉博士与韩国高级科学技术研究所的Sung Chul Kim博士进行为期24个月的合作研究项目，内容涉及聚氨酯-不饱和聚酯互穿网络的基本方面。具体地说，合作者将开发(1)用于描述聚氨酯-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和确定产生所需最终用途的最佳工艺条件奠定坚实的基础，研究人员寻求能够针对特定应用开发新树脂或修改现有树脂，并更好地控制加工操作。虽然拟议的合作项目是对一个重要的聚合物混合系统的基础研究，但它的成功完成可能对为特定应用量身定做的新产品的开发产生重要影响。这两位合作者都是备受尊敬的科学家，长期以来一直从事聚合物体系的平行研究。本项目将允许他们将他们在重要和有趣的研究中的互补才华和经验结合起来。该项目与美韩合作科学计划的目标相关，该计划旨在通过交流科学信息、想法、技能和技术以及通过在互利问题上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层面，该研究得到了国家科学基金的支持。MSM8744680。

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.
