Additional support for the existence of macromolecules came with the development of methods of molecular weight determination. 1930: Carothers in the USA synthesize polymers of definite structure through the use of established reactions of organic chemistry and the elucidation of the relationship between structure and properties of polymers. These researches were brilliantly successful and finally dispelled the mysticism surrounding this field of chemistry. One outstanding result of Carothers' work was the commercial development of nylon. Nylon stockings came on the market in 1940, when polymers, in terms of popular acceptance, might be said to have arrived. The theoretical, practical and economic foundations had been laid and since this date progress has been phenomena....
