“I am inclined to think that the development of polymerization is, perhaps, the biggest thing chemistry has done, where it has had the biggest effect in everyday life. The world would be a totally different place without artificial fibres, plastics, elastomers, etc. Even in the field of electronics, what would you do without insulation? And there you come back to polymers again.”

“Dear Colleague, Leave the concept of large molecules well alone; organic molecules with a molecular weight above 5000 do not exist. Purify your products, such as rubber, then they will crystallize and prove to be lower molecular substances. Organic molecules with more than 40 atoms do not exist. Molecules cannot be larger than the crystallographic unit cell, so there can be no such thing as a macromolecule.”

“My colleagues were very skeptical about this change, and those who knew my publications in the field of low molecular chemistry asked me why I was neglecting this interesting field and instead was working on a very unpleasant field and poorly defined compounds, like rubber and synthetic polymers. At that time the chemistry of these compounds often was designated, in view of their properties, as Schmierenchemie ('grease chemistry').”

“The evolvement of our present-day understanding of polymeric structures occurred in the early 1920s. Thus, Staudinger et al. firmly established the existence of macromolecules. Others, by X-ray analyses and careful use of molecular weight determinations, confirmed his findings. In 1929, a series of outstanding investigations were carried out by Carothers on other polymeric materials. This resulted in much of today’s knowledge and understanding.”
