ABSTRACT:
The instant invention relates to compositions comprising a copolymer of sulfur dioxide and one or more olefins in combination with a hydrocarbon oil which is a mixture of paraffinic, aromatic and naphthenic hydrocarbons having a solubility parameter of about 7 to about 8.5. The olefins are alpha olefins, at least one having a carbon number of 20 or more, more preferably a carbon number of from 20 to 40. The copolymers useful in preparing the compositions of the instant invention are crystalline solids, which are combined with a sufficient amount, preferably from about 5 to 24 pph, of the hydrocarbon oil to yield flexible materials. The above compositions are useful as coatings.
