Synthesis and Characterization of Functionalized Polyethylene Surfaces

小行星9308414 我们建议通过表面聚合来改性聚烯烃聚合物。 我们的目标是调整现有的合成方法，并开发新的程序，将引发剂纳入聚烯烃的表面界面。 所提出的反应和方法在溶液状态研究和前期工作中有先例。 我们的合成被设计为将光谱标记，以便于表征表面聚合之前和之后的改性聚合物。 XPS 光谱、红外光谱和常规物理分析如接触角分析将用于表征改性表面。 荧光标记结合淬灭基团在表面上或在溶液中的其他地方将被用来研究这些接口的2-和3-维字符和这些接口上的接枝聚合的效果。 我们提出的程序承诺提供现有接枝化学无法提供的合成控制水平。 ***

9308414 Bergbreiter We propose to modify polyolefins polymers by surface polymerization. We aim to adapt existing synthetic methods and develop new procedures to incorporate initiators into the surface interphase of polyolefins. The proposed reactions and methods have precedent in solution-state studies and in preliminary work. Our syntheses are designed to incorporate spectroscopic labels to facilitate characterization of the modified polymers before and after surface polymerizations. XPS spectroscopy, IR spectroscopy and conventional physical analyses such as contact angle analysis will be used to characterize the modified surfaces. Fluorescent labels in conjunction with quenching groups elsewhere on the surface or in solution will be used to study the 2- and 3- dimensional character of these interfaces and the effect of graft polymerization on these interfaces. Our proposed procedures promise to provide levels of synthetic control not available with existing grafting chemistry. ***
