Opis

Offers tools for the analysis, prediction and creation of various polymer blends, an area of commercial potential. This book explores and describes the use of association models to treat hydrogen bonding in polymer mixtures, illustrating its broad utility. It adapts this approach to a description of the phase behavior of polymer mixtures.
