of all the groups of industrially important polymers, silicones assume the widest variety of forms and g~ into the broadest range of applications. Silicone resins, rubbers, fluids, emulsions, greases, a i d water repellents are among the many products representative of this new group of engineering materials which have evolved out of the unique characteristics of organosilicon cornpounmd~.a i d are now influencing the product design, opera Ling, and maintenance practices o f man? different industries. This symposium was organized hj t h e Divisions of Industrial and Engjneetng ( h e m i s t y arid Paint, Plastics, and Printing La& Chemistry to review the latest developments in the more import a n t and rapidly growing types of sillicoiae applications. These applications and the silicone properties making them possible become more significant against the background of the introductory arise from the basic paper which shows ~ Q W the? nature of the organic chemistry o f hilieon, partic.ulasly from the nature of the siloxane bond, and the type, n u n h e r , and arrangement of suhslituent organic groups on silicon.
