Abstract
CARBIDE research people had for many years watched a hard, unknown polymer form in pipelines and cylinders long in ethylene oxide service. They referred to it as ivory. Now this ivory is in a salable form—Polvox resins. Behind this transformation lies a history of product development. The first thought was to characterize this ivory polymer t o see if its formation could be prevented. However, as a basic producer of ethylene oxide and its derivatives the company also wanted to learn more about this unknown polymer. This curiosity led to a literature search that disclosed work showing that high polymers of ethylene oxide could indeed be formed in the presence of a catalyst. The reaction rates were extremely low. Under laboratory conditions, polymer was formed at a conversion rate of less than 1... per week, but the basic mechanism of the polymerization reaction was established. With this much to go on, our market development people ...
