The development of phosphinated styrene-butadiene rubber

汽车轮胎由许多部件组成，每个部件都相互配合，以最大限度地提高整体性能。两种最重要的成分是丁苯橡胶（SBR）和丁基橡胶，它们分别作为轮胎的胎面材料和不透气的内衬出现。轮胎性能在轮胎行业中通常用“魔三角”来描述，包括耐磨性（轮胎磨损）、滚动阻力（行驶里程）和牵引力（安全性）。这些领域的改进通过限制与购买轮胎、燃料和轮胎废物相关的成本、减少与汽车旅行相关的排放、减少与汽车碰撞相关的伤亡人数，为加拿大人带来直接利益。这个NSERC联盟项目涉及西安大略大学的Joe B. Gilroy教授和Paul J. Ragogna教授与ARLANXEO（一家生产SBR和丁基橡胶的跨国公司，在加拿大有大量业务）之间的合作。培养博士后1名，本科生暑期研究员2名。最初的努力将集中于开发一种方法，将磷化氢基团引入SBR的聚合物主链，以创造一种被称为磷化SBR （PSBR）的新产品。通过与ARLANXEO的合作，我们将确定PSBR所需的最佳磷含量，以促进轮胎制造过程中使用的PSBR和填料之间的相互作用。我们将在PSBR进入制造过程之前和之后对其进行测试，并评估PSBR对轮胎性能“魔三角”的潜在影响。随着项目的进行，丁基橡胶也可能进行类似的研究。由于SBR和丁基橡胶的全球市场每年价值超过40亿美元，而ARLANXEO是全球最大的SBR生产商，因此PSBR的发展具有为加拿大带来经济活动的巨大潜力。这一经济活动将为加拿大人创造就业机会和财富。

Automotive tires are constructed from numerous components, each working in cooperation with the others to maximize overall performance. Two of the most important components are styrene-butadiene rubber (SBR) and butyl rubber, which appear in tires as the tread material and gas-impermeable inner lining, respectively. Tire performance is generally described in the tire industry by the 'magic triangle' that includes abrasion resistance (tire wear), rolling resistance (mileage), and traction (safety). Improvements in these areas offer direct benefit to Canadians by limiting the costs associated with the purchase of tires and fuel and tire waste, reducing emissions associated with automotive travel, and reducing the number of fatalities and injuries associated with automotive collisions. This NSERC Alliance project involves a collaboration between Professors Joe B. Gilroy and Paul J. Ragogna at the University of Western Ontario and ARLANXEO, a multinational company that produces both SBR and butyl rubber, with significant operations in Canada. It will create training opportunities for 1 postdoctoral researcher and 2 undergraduate summer researchers. Initial efforts will focus on the development of a method for the introduction of phosphine groups to the polymer backbone of SBR to create a new product known as phosphinated SBR (PSBR). Through collaboration with ARLANXEO, we will determine the optimal phosphorus content of PSBR required to promote interactions between PSBR and fillers used in the tire manufacturing process. We will test PSBR before and after it has been subjected to the manufacturing process and will assess the potential impact of PSBR on the 'magic triangle' of tire performance. As the project proceeds, similar studies for butyl rubber may also be conducted. The development of PSBR has excellent potential to generate economic activity for Canada as the global markets for SBR and butyl rubber are worth more than 4 billion USD annually and ARLANXEO is the largest producer of SBR globally. This economic activity will create jobs and generate wealth for Canadians.
