Chemistry of Polyurethanes

This book attempts to link in a general concept, organised in a systematic manner, the most important knowledge, data and information concerning the chemistry and technology of polyols for polyurethanes. This general point of view resulting from the fact that all polyols used for polyurethanes have many things in common will be presented. Polyurethanes are obtained by the reaction of an oligomeric polyol (low molecular weight polymer with terminal hydroxyl groups) and a diisocyanate (or polyisocyanate). The structure of the oligomeric polyol used for polyurethane manufacture has a very profound effect on the properties of the resulting polymer.The present book is dedicated to these very important raw materials used to build the polyurethane polymeric architecture: and covers chemistry and technology of oligomeric polyol fabrication, properties of these hydroxyl terminated oligomers and the effects of the oligomeric polyol structure on the resulting polyurethane properties.
