This discovery marked the beginning of an era, which revolutionized the field of chemistry, in particular, the field of polymer chemistry in many aspects and saw an avalanche of patents and publications. Unlike typical academic discoveries, this invention did not stop at the academic labs, but led to the development of a large-scale process that produces about 180 million tons of polyolefins (annually) today. 1 But the very obvious question that comes to our mind is what prompted Prof. Ziegler to react ethylene with the two components (that we will discuss later in this chapter)? It was not an overnight realization, but instead, it was rational analysis of a serendipitous observation and systematic experimentation by Prof. Ziegler.</p>1 aChikkali, S., H.1 aPatel, K.1 aNetalkar, S.  uhttp://library.ncl.res.in/content/insertion-or-ziegler-natta-polymerization-olefins-science-and-technology01149nas a2200133   4500008004100000245003600041210003600077260001400113300000900127520077600136100001900912700001700931856006700948       2017                        eng d00aIntroduction to organometallics0 aIntroduction to organometallics  bCRC Press  a1-303 a<p>Polymers are gigantic macromolecules that are constructed by linking together a large number of smaller molecules called monomers through the process of polymerization. Polymer chemistry has evolved from a primitive, pragmatic discipline in the early 1920s to a well-established academic course today. The early efforts by Hermann Staudinger laid the foundation of rational polymer science and today it is nearly well understood as any other contemporary science. The fundamentals of chemistry and physics of polymers are detailed in many text books and we refer the reader to dedicated main stream polymer science books. 1 Nevertheless, the subject is forging ahead and is conquering new territories, and understanding of these new frontiers is equally important.</p>1 aChikkali, S.H.1 aNetalkar, S.  uhttp://library.ncl.res.in/content/introduction-organometallics
