Preface

The present work is destined to the technicians of the polyurethanes area (PU's). In it we tried to publish the most recent technical knowledge, relative to this area of the polymeric chemistry.

In 1993, we published the first edition of the book "Química e Tecnologia dos Poliuretanos", and in 1998, the second edition.

In this third updated edition also published in English (Chemistry and Technology of Polyurethanes) we tried to include the new technological progresses happened in polyurethane area.

In the book "Chemistry and Technology of Polyurethanes" and in www.poliuretanos.com.br, we include a Catalog of Companies and Polyurethanes Suppliers where your Company can advertise your products, to the Global Market.
