While polyethylene catalysis is a mature field, global needs for stronger, lighter materials and growth in polyethylene demand drives ongoing innovation in product design. Such ongoing innovation has enabled, and continues to enable, the replacement of heavier materials with (such as glass and cardboard) in product packaging, thereby offering a significant environmental advantage in terms of fuel efficiency and reduced greenhouse gases in product transport. Furthermore, not all plastic food packaging is currently recyclable due to the need to mix polyolefin materials with other materials to create good barrier properties and keep food fresh. Enhanced control over polyethylene structure and co-monomer incorporation into the polymer backbone, are expected to lead to vastly improved rheological and mechanical polymer properties. Such improvements could be used to produce multifunctional polyolefins that are also 100% recyclable. This would have a tremendous effect on reducing the amount of material going into landfills and would reduce the amount of virgin plastic resin needed by allowing recycling of existing material. In this project, we aim to use step-wise oligomer synthesis to make materials with highly controlled polymer structures so that we can investigate their performance. If successful, it could be envisaged that a longer collaboration be engaged in between NOVA Chemicals and the scientists at Université de Sherbrooke to prepare such products by economically viable routes.

虽然聚乙烯催化是一个成熟的领域，但全球对更强、更轻材料的需求以及聚乙烯需求的增长推动了产品设计的持续创新。 这种持续的创新已经实现并将继续实现在产品包装中用较重的材料（如玻璃和纸板）替代较重的材料，从而在产品运输中的燃料效率和减少温室气体方面提供显著的环境优势。 此外，目前并非所有的塑料食品包装都是可回收的，因为需要将聚烯烃材料与其他材料混合以产生良好的阻隔性能并保持食品新鲜。 对聚乙烯结构和共聚单体并入聚合物主链的增强的控制预期导致极大地改进的流变和机械聚合物性质。 这种改进可用于生产100%可回收的多官能聚烯烃。 这将对减少进入垃圾填埋场的材料数量产生巨大影响，并通过允许回收现有材料来减少所需的原始塑料树脂的数量。 在这个项目中，我们的目标是使用逐步低聚物合成来制造具有高度可控的聚合物结构的材料，以便我们可以研究它们的性能。 如果成功的话，可以设想NOVA化学品公司与舍布鲁克大学的科学家进行更长时间的合作，通过经济上可行的途径制备这种产品。
