Plastics are made from polymers and polymer manufacture represents one of the largest and most dynamic sectors of the chemical industry. Companies are targeting better performing polymer materials derived from more economical and environmentally friendly (bio-renewable) feedstocks. These improvements are often driven by chemical advancements in polymer synthesis research, such as the work supported by this award. It is critical to the field of polymer chemistry to improve the basic understanding of the relationships between polymer structure and the properties of the resulting plastic, which is a primary goal of this research. Undergraduate students, including low income and first generation college students, perform laboratory work for this study and receive valuable training to prepare them for graduate school and/or employment in the chemical industry. With the support from the Macromolecular, Supramolecular, and Nanochemistry Program of the NSF Division of Chemistry, Prof. Robertson of Northland College and Prof. Carney of the University of Wisconsin-Eau Claire conduct collaborative research to better understand the properties of ruthenium catalysts in polymerization reactions. Specifically, this project focuses on making advancements in five key areas: (1) preparation of polymers from bio-renewable monomers, such as 5-hydroxymethylfurfural (HMF), (2) polymer alternatives to polyurethanes (found in many paints, varnishes, adhesives, and foams), (3) increasing the utility of commodity plastics, (4) depolymerization methods to produce useful chemicals from waste plastics, and (5) synthesis of new ruthenium compounds to better understand the impacts of chemical structure on the catalyst's performance. Toward this end, the research team is synthesizing and studying new ruthenium catalysts with structurally versatile N-phosphinoamidine and beta-diketimine ligand backbones.

塑料是由聚合物制成的，聚合物制造是化学工业中最大和最具活力的部门之一。公司的目标是从更经济、更环保的(生物可再生)原料中获得性能更好的聚合物材料。这些改进通常是由聚合物合成研究中的化学进步推动的，例如该奖项支持的工作。提高对聚合物结构和所得塑料性能之间关系的基本认识是聚合物化学领域的关键，这也是本研究的主要目标。本科生，包括低收入和第一代大学生，为这项研究进行实验室工作，并接受有价值的培训，为他们进入研究生院和/或在化学工业就业做准备。在美国国家科学基金会化学部大分子、超分子和纳米化学项目的支持下，Northland学院的Robertson教授和威斯康星大学Eau Claire大学的Carney教授开展了合作研究，以更好地了解Ru催化剂在聚合反应中的性质。具体地说，该项目集中在五个关键领域取得进展：(1)从生物可再生单体，如5-羟甲基呋喃(HMF)制备聚合物，(2)替代聚氨酯的聚合物(存在于许多油漆、清漆、粘合剂和泡沫中)，(3)提高商品塑料的利用率，(4)从废塑料中解聚生产有用的化学品，以及(5)合成新的Ru化合物，以更好地了解化学结构对催化剂性能的影响。为此，该研究小组正在合成和研究具有结构多功能的N-膦酰胺和β-二酮硫胺配体骨架的新型Ru催化剂。
