Polyolefins is the collective name for polyethylene (PE) and polypropylene (PP) which are amongst the most widely used plastics today, accounting for more than half of total plastics consumption in the developed world. Available for the first time as a two-volume set, Polyolefin Blends and Polyolefin Composites comprehensively summarize and collect many of the technical research accomplishments conducted on blends and composites of polyolefin. The first books to focus exclusively on this subject, they serve as a "one stop" reference resource for the important research advances and accomplishments in recent years, with major emphasis given to the new area of polyolefin nano-blends and polyolefin nano-composites.
