Second in a series, and reflecting their commercial significance, this book focuses on the commercial use and process improvements of resins produced with metallocene, single site and other modern catalytic methods. Research to broaden the scope of applications and shorten production cycles is presented. New and improved polymer blends resulting from the use of new catalysts and improved polymer compatibility are explored as well as new applications becoming possible due to improved and balanced properties. Chapters cover use in extrusion, film manufacture, injection molding, foam production, fiber spinning, composites and new applications. Precise testing methods, material characterization, polymer morphology and crystallization are the focus of another section of the book.
