Claims
- 1. 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 leat one monomer having the structure: ##STR4## 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, or hexamethylene, thereby forming a cyclic epoxide.
- 2. The composition of claim 1 wherein the .alpha.-olefin of (1) (a) is 1-hexene.
- 3. The composition of claim 1 wherein the .alpha.-olefin of (1) (a) is a mixture of 1-butene and 1-hexene.
- 4. The composition of claim 1 wherein the nonconjugated polyene of (1) (b) is selected from the group consisting of 1,4-hexadiene, 4-methyl-1,4-hexadiene, and 5-methyl-1,4-hexadiene.
- 5. The composition of claim 1 wherein the nonconjugated polyene of (1) (b) is selected from the group consisting of 1,4-hexadiene, 1,5-hexadiene, and 1,7-octadiene.
- 6. The composition of claim 1 wherein the saturated polymer of (2) is poly(propylene oxide).
- 7. The composition of claim 1 wherein the saturated polymer of (2) is prepared from a mixture of ethylene oxide and propylene oxide.
- 8. The composition of claim 1 wherein the blend ratios are between 80:20 and 20:80.
