Abstract
AbstractMercuric chloride polymerized diketene at low temperature. The molecular weight of the acetone‐insoluble and dioxane‐soluble fraction of the polymer was 1630.From the alcoholysis of the polymer and the infrared spectrum of the polymer, the molecular structure of the polymer was considered to be the open chain polymer of vinylaceto‐β‐lactone. Consequently, the molecular structure of diketene was also believed to be vinylaceto‐β‐lactone, although the assignments of the five strong bands in the doublebond region still remain in question.
