Abstract
Di or polyfunctional macromolecular compounds having a terminal functional group at each end of the molecule are produced by selectively cleaving the carbon-carbon double bonds of an unsaturated polymer by the oxidizing action of a ruthenium tetroxide oxidizing system. The compounds are useful as components in crosslinked plastics materials, in binders for rocket fuels, and as components in tri or polysequential copolymers.
