项目摘要
Research Summary: This is an Engineering Research Equipment Grant. A gel permeation chromatograph (gpc) capable of operation from ambient to 150oC is provided by NSF. This instrument is capable of measuring the molecular weight distribution of important crystalline polymers that are insoluble at room temperature, such as polyethylene and polypropylene. It provides the most efficient means that is currently available for characterizing molecular weights of polymers. The instrument is to be used in several projects under way in this department, including one aiming at the fractionation of crystalline polymers in supercritical solvents. Innovation: The fractionation of crystalline polymers in supercritical solvents, to be analyzed by means of the high temperature gpc, represents a novel concept. The other analytical tasks outlined in the proposal that require use of the gpc also represent novel research. Practical Significance: The practical significance of the research which requires use of the instrument includes the design of more efficient fractionation processes for crystalline polymers, the development and study of polymer blends with new physical properties, and the assessment of a new process for coal liquefaction. More specifically, polymer fractionation of the type described might be applicable to high pressure polyethylene processes and the purification of isotactic polypropylene. In addition, novel and useful polymer morphologies might be generated by precipitation from supercritical solution. The high temperature gpc will be necessary for the analysis of the products generated in most of the studies referred to. Recommendation: An award of $35,445 in FY 1987 is recommended, with SUNY-Buffalo providing $19,085 in matching funds.
研究综述:这是一项工程研究设备助学金。美国国家科学基金会提供了一种能够在常温到150℃下工作的凝胶渗透色谱仪(GPC)。该仪器能够测量重要的结晶聚合物的分子量分布,这些聚合物在室温下是不溶的,如聚乙烯和聚丙烯。它提供了目前可用于表征聚合物分子量的最有效的手段。该仪器将用于该部门正在进行的几个项目,包括一个旨在超临界溶剂中结晶聚合物的分馏的项目。创新:结晶聚合物在超临界溶剂中的分级,将通过高温GPC进行分析,这代表了一个新的概念。提案中概述的需要使用GPC的其他分析任务也代表了新的研究。实际意义:这项需要使用该仪器的研究的实际意义包括设计更有效的结晶聚合物分馏工艺,开发和研究具有新物理性质的聚合物混合物,以及评估煤炭液化的新工艺。更具体地说,所述类型的聚合物分级可能适用于高压聚乙烯工艺和等规聚丙烯的提纯。此外,从超临界溶液中沉淀还可能产生新的有用的聚合物形态。高温凝胶渗透色谱对于大多数研究中产生的产物的分析是必要的。建议:建议在1987财政年度提供35,445美元,纽约州立大学布法罗分校提供19,085美元的配套资金。
