9417523 Composto The purpose of this U.S.-Czech research project between Dr. Russell Composto of the University of Pennsylvania and Dr. Petr Vlcek of Czech Academy of Sciences' Institute of Macromolecular Chemistry is to synthesize novel polymeric materials to study polymer adsorption at the polymer/solid interface. To do this, the researchers will use anionic-living and group-transfer polymerization techniques to prepare block copolymers and end- functionalized polymers which bind to oxide surfaces. These specialty polymers will be blended with a matrix polymer and spun-cast on an inorganic substrate. The composition profile, amount absorbed, grafting density of the adsorbed species, and the strength of adsorption will be measured. Results are expected to contribute to our basic knowledge of polymer adhesion and may have relevance to technological problems in the coatings industry. This project in materials research fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Eastern Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence.

9417523 Composto 宾夕法尼亚大学的 Russell Composto 博士和捷克科学院高分子化学研究所的 Petr Vlcek 博士之间的这个美国-捷克研究项目的目的是合成新型聚合物材料，以研究聚合物在聚合物/坚固的界面。 为此，研究人员将使用阴离子活性和基团转移聚合技术来制备与氧化物表面结合的嵌段共聚物和末端官能化聚合物。 这些特种聚合物将与基质聚合物混合并纺丝到无机基材上。 将测量成分分布、吸附量、吸附物质的接枝密度以及吸附强度。 研究结果预计将有助于我们了解聚合物附着力的基本知识，并可能与涂料行业的技术问题相关。 该材料研究项目通过使美国和东欧的专家能够结合互补的人才并在共同感兴趣和能力强的领域共享研究资源，实现了推进科学知识的计划目标。
