En 1920, el químico orgánico Hermann Staudinger, publicó su célebre artículo Über Polymerisation (Sobre Polimerización), proponiendo la existencia de largas cadenas de muy alto peso molecular, en las cuales los átomos se mantienen juntos por medio de uniones químicas covalentes. En el transcurso de estos 100 años, la Química de los Polímeros ha avanzado rápidamente, siendo reconocida hoy como una de las ramas más activas en investigación, desarrollando nuevos productos útiles con una amplia gama de aplicaciones. Este trabajo trata sobre aspectos relevantes de la historia de la Química Macromolecular. Se mencionan algunos de los nombres de los investigadores más importantes que ayudaron a desarrollar esta ciencia durante el siglo XX y también se nombran algunos de los profesores que iniciaron la enseñanza de los polímeros en México, específicamente en la Universidad Nacional Autónoma México (UNAM).]]></p></abstract>
