This award supports cooperative research in polymers to be conducted by Harry Frisch of the Research Foundation of New York (SUNY-Albany) and Glaucione de Barros of the Federal University of Ceara in Fortaleza, Brazil. They will study novel methods of polymer modification by the formation of interpenetrating polymer networks. Such networks could result in more valuable modified natural polymers with significantly enhanced physical properties. Improved mechanical properties of natural rubber such as increased strength, frictional and impact resistance will be sought in work that requires little sophisticated equipment or materials. For example, ionic or electrical conductivity can be improved by suitable material doping. Network composites made of carnauba wax can produce a material of lower crystallinity. This collaboration represents an excellent fit between the research interests of the investigators. Additionally, the proposed interaction between them will result in new graduate programs for students at both institutions. The project is expected to result in a new polymer research capability in Brazil and in substitute products from natural sources, of mutual benefit as petroleum supplies become scarce or prices rise.

该奖项支持纽约研究基金会(纽约州立大学奥尔巴尼分校)的Harry Frisch和巴西福塔莱萨塞拉联邦大学的Glaucione de Barros在聚合物领域的合作研究。他们将通过形成互穿聚合物网络来研究聚合物改性的新方法。这样的网络可以产生更有价值的改性天然聚合物，具有显著增强的物理性能。在不需要复杂设备或材料的工作中，将寻求改善天然橡胶的机械性能，如增加强度、摩擦和抗冲击性。例如，离子或电导率可以通过适当的材料掺杂来改善。由巴西棕榈蜡制成的网络复合材料可以生产结晶度较低的材料。这种合作代表了研究人员的研究兴趣之间的完美契合。此外，他们之间拟议的互动将导致两所大学的学生开设新的研究生课程。该项目预计将在巴西产生新的聚合物研究能力，并在石油供应变得稀缺或价格上涨的情况下产生互惠互利的天然来源的替代产品。
