The aim of this proposal is to acquire a High-Temperature Gel Permeation Chromatograph (HT-GPC) necessary to analyze the molecular weight distribution (MWD) of polymers which are insoluble in any solvent at room temperature. The knowledge of the MWD is essential for all scientists working in the domain of polymer science and engineering, as this parameter is intimately linked to mechanical, rheological, process-related, optical and durability of the polymer. Determination of the MWD is usually performed in GPCs, operating at room temperature or slightly above. However, many polymers, such as the ones impacted by this proposal, are only soluble at high temperature (above 140 oC), necessitating a specific chromatographic unit which can operate under such conditions. The instrument we request will be used by the numerous researchers working on polymer-related domains at the Université de Sherbrooke (UdS), and will be located in the department of chemistry of UdS. In particular, it will be indispensable for the analysis of polyolefins prepared/processed in the group Claverie, Soldera and Huneault, polyacrylamides prepared in the group Zhao, polyesters processed in the group Elkoun, and complex macromolecular architectures prepared in the group Harvey. No such instrument is currently present at UdS. With the recent arrival of the PI at UdS, acquisition of this instrument becomes ineluctable, as functional instruments able to withstand the volume of analysis required to support the research of the coPIs are not available in Canada. The urgency of the acquisition is reinforced by the fact that out of the two existing vendors, one will discontinue the HT-GPC line next year, putting the other one in a situation of monopoly. Beyond its significant impact on the research programs shown below, the instruments will be pivotal for the training efforts of HQPs associated to polymer science. As the instrument will be placed in an accessible facility, staffed with specifically trained personnel, we envision that a minimum of 80 HQPs will be using this HT-GPC.

本提案的目的是获得一台高温凝胶渗透色谱仪（HT-GPC），用于分析室温下不溶于任何溶剂的聚合物的分子量分布（MWD）。MWD 的知识对于分析聚合物的分子量分布（MWD）至关重要。所有从事聚合物科学和工程领域工作的科学家，因为该参数与聚合物的机械、流变、工艺相关、光学和耐久性密切相关，MWD 的测定通常在 GPC 中进行。然而，许多聚合物（例如受本提案影响的聚合物）只能在高温（高于 140 oC）下溶解，因此需要能够在此类条件下运行的特定色谱装置。被舍布鲁克大学 (UdS) 的众多从事聚合物相关领域的研究人员使用，并且将位于舍布鲁克大学化学系，特别是对于以下领域来说，它将是不可或缺的。对 Claverie、Soldera 和 Huneault 组制备/加工的聚烯烃、Zhao 组制备的聚丙烯酰胺、Elkoun 组加工的聚酯以及 Harvey 组制备的复杂大分子结构的分析目前 UdS 没有此类仪器。最近 PI 到达 UdS，购买该仪器变得不可避免，因为能够承受支持 coPI 研究所需的分析量的功能仪器是现有的两家供应商中，其中一家将于明年停止生产 HT-GPC 产品线，这使得另一家处于垄断地位，这进一步加剧了收购的紧迫性。如下所示的研究计划，这些仪器对于与聚合物科学相关的总部人员的培训工作至关重要，因为该仪器将放置在易于使用的设施中，并配备经过专门培训的人员，我们预计至少有 80 名总部人员将使用该仪器。高温凝胶渗透色谱。
