ABSTRACT:
A double substitution of pentafluorsulfur on diacetylene by a reaction of diacetylene with pentafluoro sulfur bromide, followed by a dehydrobromineaction with potassium hydroxide. The substituted diacetylene polymerizes in the liquid and gas phases. The polymer is useful as a coating and surface-treatment agent.
