Because of the many important new developments in other branches of science, some scientists fail to recognize that the volume of polyolefins produced annually is greater than that of all metals. Hence, the American Chemical Society s"ponsored symposia on the History of Polyolefins at its national meeting at Miami Beach in the Spring of 1985 and a Macromolecular Secretariat on Advances in Polyolefins at its national meeting in Chicago in the fall of that year. The books on the proceedings of these landmark symposia and another book entitled "The Chain Straighteners" by Dr. F. M. McMillan will provide the scientist with background information which is essential for re- searchers in this important phase of polymer science. The presentations at these international symposia and the publica- tions of the reports presented, would not be possible without the dedicated efforts of our assistant editors and publisher. The list of contributors to ADVANCES IN POLYOLEFINS includes most of the leaders in this field, such as Dr. Mark, Mandelkern, Bruzzone, Hsieh, Kaneda, Chien, Tait, Karol, Kaminisky, Scott, Cook, Mirabella, Samuels, Kanamoto and Vigo.These reports covered many phases of polyolefin science and technol- ogy, ranging from elastomers, single crystals, film and fibers to char- acterizations by modern instrumentation and many new innovations in catalysis which have brought about a revolution in polyolefin production.

The first concern of scientists who are interested in synthetic polymers has always been, and still is: How are they synthesized? But right after this comes the question: What have I made, and for what is it good? This leads to the important topic of the structure-property relations to which this book is devoted. Polymers are very large and very complicated systems; their character­ ization has to begin with the chemical composition, configuration, and con­ formation of the individual molecule. The first chapter is devoted to this broad objective. The immediate physical consequences, discussed in the second chapter, form the basis for the physical nature of polymers: the supermolecular interactions and arrangements of the individual macromolecules. The third chapter deals with the important question: How are these chemical and physical structures experimentally determined? The existing methods for polymer characterization are enumerated and discussed in this chapter. The following chapters go into more detail. For most applications-textiles, films, molded or extruded objects of all kinds-the mechanical and the thermal behaviors of polymers are of pre­ ponderant importance, followed by optical and electric properties. Chapters 4 through 9 describe how such properties are rooted in and dependent on the chemical structure. More-detailed considerations are given to certain particularly important and critical properties such as the solubility and permeability of polymeric systems. Macromolecules are not always the final goal of the chemist-they may act as intermediates, reactants, or catalysts. This topic is presented in Chapters 10 and 11.
