Farbenindustrie, there had flowed from that laboratory a remarkable series of new synthetic polymers, including the first commercial polystyrene. The resultant embarrassing discovery that polystyrene made in a big reactor differed seriously from that made in laboratory apparatus left Mark with a continuing interest in the properties of polymers made at different temperatures. He later published a detailed study which described those differences in terms of a theoretical equation developed by Prof.
Actually, it was investigated further, although not by Marvel. DuPont, for whom he was a consultant, tried out the reaction but did not see any commercial possibilities. Their negative conclusion probably reflects both the inherent difficulties in the process and their limited expertise and interest in high polymers at that time (Wallace Carothers' polyamide precursor to nylon was then a new laboratory curiosity, and high-pressure polyethylene had not yet been discovered). It would appear that this is another case of a promising lead being discovered ahead of the most propitious time.
36 The Chain Straighteners aneous description of the Zieglers, given to me by an 'outsider' who had become a friend and admirer: You have this man who is intensely proud, intensely competent as a scientist, but no ivory tower man. A family man, very proud of his son, very proud of his grandson. A man who'd suffered a lot, because he'd built up his research institute at Halle, and all this had been destroyed, and he'd had to come away with only the possessions he could carry in a car and start again at the Max Planck.
