The Technology of Plastics and Resins [antikvár]

PREFACE This book is based upon a college course in the Chemistry of Plastics and Resins offered at Boston University by one of the authors. At the time that the course was originally planned, a survey of the books available on plastics and resins revealed that they were written either for graduate students of chemistry or for persons who wanted to know about the practical applications of plastics and resins without paying much attention to the chemical reactions involved in their preparation. Since the preparation of new plastics has been accompanied by improvements in processing techniques, it is desirable for the student to become familiar with both of the fundamental phases and try to correlate them as much as possible. Our objective, therefore, has been to develop a book which would be suitable for students who have had introductory courses in General Chemistry and Organic Chemistry, and which would serve as an adequate introduction to both the chemistry and the practical utilization of plastics and resins. The matériái should alsó be of interest to men in industry who wish to refresh their knowledge of the fundamentals underlying plastics development and technique. The book is divided into three sections. The first section, consisting of six chapters, is the theoretical and generál part, in which terms are explained, types and mechanisms of polymerization are discussed, and the relationship between various physical properties and the structure of plastics and resins is presented. In the second section (thirteen chapters), the methods of preparation and the properties and uses of the more important resins and plastics are discussed. The third section (six chapters) contains a discussion of fabncation techniques, e.g., compounding and mold designs, together with molding, casting, laminating and coating procedures. The authors are especially indebted to Dr. Ernst A. Hauser of the Massachusetts Institute of Technology who read the originál manuscript and made numerous suggestions for its improvement. We are alsó grateful to the several specialists who have read certain sections of the manuscript. While most of the suggestions made by these reviewers have been accepted and incorporated in the book, the authors hasten to add that they alone accept full responsibility for all statements made in this book. Criticisms and suggestions for improvement will be welcomed.
