Despite the fact that since ages man has been using naturally occurring substances, like starch, cellulose, and proteins, which are actually polymeric materials, for his food, clothing and for varied applications, it was not until the third decade of this century that the macromolecular character of these substances was universally accepted.1 The science of high polymers began to emerge only in the 1920s when H. Staudinger firmly established the existence of macromolecules through his brilliant investigations.2,3 Once the possibility of macromolecules had been grasped, many methods were rapidly developed for preparing them synthetically. Outstanding contributions in this regard came from W. Carothers who started, in 1929, a series of investigations of functionality and polymer formation. Rapid progress in polymer science has continued ever since. In the few decades following 1930 there has been a tremendous development of chemical industries devoted exclusively to production and processing of polymeric compounds, the number and volume of which are constantly increasing.
