Polyisobutylene (PIB) is a workhorse polymer that is found in a multitude of products, ranging from chewing gum, to tires, to engine oil and gasoline additives. Although commercially produced in large quantities since the 1940s, PIB chemistry was a mystery—scientists weren't sure how the reaction mechanism that creates the polymer happens at the molecular level, which limited further potential.
However, a collaboration between the University of Pittsburgh's Swanson School of Engineering and Wickliffe, Ohio-based Lubrizol Corporation has unlocked the secrets of PIB's reaction mechanism. The group's findings were published this month in the journal ACS Catalysis.
Principal investigator is Karl Johnson, the William Kepler Whiteford Professor in the Swanson School's Department of Chemical & Petroleum Engineering. Funding for the research was provided by Lubrizol, which in 2014 established a $1.2 million strategic partnership with the Department and Swanson School to jumpstart research innovation that also offers opportunities for undergraduates to participate.
