0307107TonelliThis three-year award for US-Spanish collaboration in polymer processing involves Alan Tonelli and C. Maurice Balik of North Carolina State University and Marian Gomez of the Institute of Science and Technology of Polymers in Madrid, Spain. The objectives of the project are to explore systematically the use of inclusion compounds as a way of enhancing the properties of isotactic polypropylene(i-PP). They will determine the conditions under which cyclodextrin inclusion compounds (CD-ICs) can be formed with i-PP and the elastomers used in its blends, study the morphology and properties of i-PP after its coalescence from its CD-IC, study the properties and morphology of intimate i-PP/elastomer blends formed via coalescence from their common CD-IC crystals, and compare the properties of i-PP/elastomer blends processed via the CD-IC route with materials of identical composition but processed via traditional methods. The US researchers bring to the collaboration expertise in the preparation of polymer CD-ICs and characterizing them with NMR, FTIR, x-ray diffraction and thermal analysis techniques. Their expertise also includes polymer morphology, sorption, and diffusion of small molecules through polymers, and structure-property relationships. This is complemented by the Spanish researcher's extensive experience in the preparation and characterization of i-PP/elastomer blends and composites. The results of the collaboration are expected to an improved understanding of the mechanisms responsible for the unique morphologies and properties polymers might obtain after coalescence from their CD-ICs. The broader impact of this research lie in the opportunity to produce new and improved materials based on i-PP.

0307107 Tonelli这个为期三年的奖项是为美国和西班牙在聚合物加工方面的合作而颁发的，获奖者包括Alan Tonelli和C.北卡罗来纳州州立大学的莫里斯·巴里克和西班牙马德里聚合物科学技术研究所的玛丽安·戈麦斯。该项目的目标是系统地探索使用包合物作为提高等规聚丙烯（i-PP）性能的一种方法。 他们将确定异丙基聚丙烯及其共混物中所用弹性体形成环糊精包合物（CD-IC）的条件，研究异丙基聚丙烯从CD-IC聚结后的形态和性能，研究通过它们共同的CD-IC晶体聚结形成的紧密异丙基聚丙烯/弹性体共混物的性能和形态，并将通过CD-IC路线加工的i-PP/弹性体共混物的性能与相同组成但通过传统方法加工的材料进行比较。美国研究人员将聚合物CD-IC制备方面的专业知识带到合作中，并使用NMR，FTIR，X射线衍射和热分析技术对其进行表征。 他们的专业知识还包括聚合物形态，吸附和小分子通过聚合物的扩散，以及结构-性能关系。 西班牙研究人员在制备和表征i-PP/弹性体共混物和复合材料方面的丰富经验对此进行了补充。 合作的结果预计将提高对负责独特形态和性能的机制的理解聚合物可能在其CD-IC聚结后获得。 这项研究的更广泛影响在于有机会生产基于i-PP的新型和改进材料。
