ABSTRACT:
There is disclosed a rubbery composition comprising a blend of between 95/5 and 5/95 weight percent of (1) a rubbery interpolymer consisting of (a) at least 80 weight percent of at least one .alpha.-olefin containing from 5 to 10 carbon atoms and (b) up to 20 weight percent of a nonconjugated polyene containing from 5 to 30 carbon atoms with (2) a saturated polymer of an .alpha.-olefin oxide prepared from at least one monomer having the structure: ##STR1## wherein R.sub.1 and R.sub.2 are selected from the group consisting of hydrogen or a lower alkyl radical containing from 1 to 8 carbon atoms and R.sub.3 and R.sub.4 are selected from the group consisting of hydrogen, a lower alkyl radical containing from 1 to 8 carbon atoms and an alkoxyalkyl radical containing up to 12 carbon atoms, an aryl radical, a haloalkyl radical containing from 1 to 12 carbon atoms and in which R.sub.3 and R.sub.4 taken together may be trimethylene, tetramethylene, or hexamethylene, thereby forming a cyclic epoxide, or (3) an unsaturated copolymer of an .alpha.-olefin oxide prepared from 80 to 99.5 weight percent of at least one monomer having the structure I; with from 0.5 to 20 weight percent of a comonomer selected from the group consisting of butadiene monoxide, isoprene monoxide, 1,2-epoxy-3-allyloxypropane (allyl glycidyl ether), 4,5-epoxy-1-hexene, 4,5-epoxy-2-hexene, 1,5-cyclooctadiene monoepoxide, 1-vinyl-3,4-epoxycyclohexane and limonene monoxide.
