The present Engage project focuses on the analysis of the physical properties of the prototypical aliphatic polymer polypropylene (PP) and the directed modification thereof through chemical additives. The project partner Polymer Recycle Inc. is a company that manufactures PP for recycling. The company is a post-industrial plastic recycling company with R&D in Quebec and manufactures reduced-size plastics as finished products. Polymer Recycle Inc. strives to increase the toughness of its products to render them more resistant to the external force and deformation when they are casted by industrial customers.To that end, the company is interested in better understanding the influence of toughness and conductivity of PP on the quality. For this project, it is important to determine the toughness of PP as a function of the content of chemical additives. The samples provided by Polymer Recycle Inc. contain different amounts of various thermoplastic elastomers (TPE). The first goal of the project is determining which formulation and weight percentage of TPE in PP is required to optimize the toughness of PP. The second goal is exploring the impact of TPE admixture on the electrical bulk conductivity of PP, the increase of which is expected to be beneficial by the company in its recycling protocol.The analysis required for this project includes testing the toughness of the composites, analysing their opto-electronic/electrical properties, their rheology, as well as their phase behavior. The equipment for testing toughness is available at the company. The complimentary equipment required for characterizing rheological, opto-electronic, and electrical properties as a function of the additive content is available at Concordia University. The results of this project will be valuable for the quality improvement of the products of Polymer Recycle Inc.

目前的Engage项目重点分析典型脂肪族聚合物聚丙烯（PP）的物理性能以及通过化学添加剂对其进行定向改性。项目合作伙伴 Polymer Recycle Inc. 是一家生产回收用 PP 的公司。该公司是一家后工业塑料回收公司，研发中心位于魁北克省，生产尺寸缩小的塑料成品。 Polymer Recycle Inc.致力于提高其产品的韧性，使其在工业客户铸造时更能抵抗外力和变形。为此，该公司有兴趣更好地了解PP的韧性和导电性对质量的影响。对于该项目，重要的是确定 PP 的韧性与化学添加剂含量的关系。 Polymer Recycle Inc.提供的样品含有不同量的各种热塑性弹性体（TPE）。该项目的首要目标是确定需要哪种配方和 PP 中 TPE 的重量百分比来优化 PP 的韧性。第二个目标是探索 TPE 混合物对 PP 整体电导率的影响，预计电导率的增加将有利于该公司的回收协议。该项目所需的分析包括测试复合材料的韧性，分析其光电/电性能、流变性以及相行为。公司备有韧性测试设备。康考迪亚大学提供了表征流变学、光电和电气特性作为添加剂含量的函数所需的免费设备。该项目的成果对于Polymer Recycle Inc.产品质量的提高具有重要意义。
