ISPAC 2021 will be a great opportunity to celebrate the Foundation of Polymer Science Centennial. In fact in 1920, Hermann Staudinger postulated for the first time that materials such as natural rubber have very high molecular weights. In a paper entitled "Über Polymerisation," Staudinger described many reactions that form high molecular weight molecules by linking together a large number of small molecules. He also named these reactions "polymerizations," meaning that individual repeating units are joined together by covalent bonds.
Hundred years of Polymer Science have shown how essential is polymer analysis and characterization, in fact many breakthroughs would not have been possible without a precise comprehension of the molecular structure of polymers obtained by new syntheses, a famous example is the case of isotactic polypropylene.
