In 1954, 1,4-cA-polyisoprene, the synthetic equivalent of natural rubber, was obtained in the laboratories of Goodrich-Gulf [22] by isoprene polymerisation with new catalysts developed by Natta, and later on 1,4-trans-polyisoprene, a synthetic analogue of gutta percha, was obtained by Natta et al. [23].

Professor Karl Ziegler was at the Max Planck Institute for Coal Research during this period working primarily with ethylene (Aufbau process) and much of his research that followed the initial discovery of the Miilheim catalyst (TiCl + AlEt ) dealt with ethylene homopolymerization and eth-ylene/propylene copolymerization. Before Ziegler disclosed his discovery in a technical publication, he disclosed his results to two industrial companies Montecatini of Italy and Goodrich-Gulf of the United States.
