This project has as its primary aim the synthesis of organic molecules that incorporate a variety of perfluorinated groups, including pentafluorothio and perfluoroalkyl. New and unique fluorinated photopolymerizable synthons will be used to form durable polymer films and coatings in which the fluorinated components partition to the surface of the incipient film. This has the potential to produce polymer films in which a fluorine-enriched overlayer is incorporated into an otherwise conventional polymer. Once prepared, systematic structure - property relationships will be determined by photoelectron spectroscopy and infrared analysis; and refractive index, dielectric constant and surface energies will also be measured.With this Award, the Organic and Macromolecular Chemistry Program continues support for the research of Professor Gary L. Gard of Portland State University, Portland, Oregon. Professor Gard studies the variations in properties of fluorinated plastics as that plastic's constituent building blocks are themselves varied. Fluorinated compounds such as those being investigated in Professor Gard's laboratory have found various applications such as solvents for polymers, perfluorinated blood substitutes, surface active agents, and as thermally and chemically stable monomers and polymers.

该项目的主要目标是合成含有各种全氟基团的有机分子，包括五氟硫代和全氟烷基。 新的和独特的氟化的光聚合的聚硅氧烷将被用于形成耐久的聚合物膜和涂层，其中氟化组分分配到初始膜的表面。 这具有生产聚合物膜的潜力，在该聚合物膜中，富氟覆盖层被并入到另外的常规聚合物中。 一旦制备完成，将通过光电子能谱和红外分析确定系统的结构-性质关系;还将测量折射率，介电常数和表面能。有了这个奖项，有机和大分子化学计划继续支持教授加里L。俄勒冈州波特兰的波特兰州立大学的加德。 Gard教授研究了氟化塑料特性的变化，因为塑料的组成成分本身就不同。 Gard教授实验室正在研究的含氟化合物已经发现了各种应用，如聚合物溶剂，全氟血液替代品，表面活性剂，以及热稳定和化学稳定的单体和聚合物。
