Unformatted text preview: A New Wor astomers Metallocene catalysts have spawned a new family of polyolefins, somewhat inelegantly called plastomers. These materials combine the properties of classic elastomers, like polyisoprene or polybutadiene, and the plastic materials like polyethylene or polypropylene—as indicated by the chart below. The ability to design and build (co)polymers with precise, narrow ranges of compositions and molecular weights has lead to materials that are tougher, smoother, more transparent and more‘sealable’ than conventional non-metailocene polyethylenes.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
