    摘要: 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.

    摘要: The instant invention relates to novel block copolymers containing olefin sulfur-dioxide segments and a process for their preparation. The olefin of choice is a "strained" olefin thus capable of reaction with SO.sub.2 in the presence of radicals at very high rates. Examples of strained olefins include cyclopropene, cyclobutene, norbornene, and the derivatives thereof. The novel block copolymers are prepared by contacting the olefin and the sulfur dioxide with a polymer under conditions of shearing degradation whereby said polymer is broken down into radical-containing segments which subsequently combine with the olefin and sulfur dioxide to form the novel copolymers described above. The polymer may be selected from the group consisting of polyisobutylene, poly(ethylene oxide), ethylene-propylene copolymers, poly(propylene oxide), polybutadiene, polyisoprene, etc. A novel block polymer formed by this preferred process shows improved properties as compared to physical mixtures of said polymer and olefin-sulfur dioxide copolymers. For example, the novel polymers formed by the preferred process of the instant invention show higher moduli and may be plasticized to higher levels while retaining good physical properties.
