Abstract
A composition comprising an ethylene/C5-C10 alpha-olefin/non-conjugated polyene interpolymer, wherein the interpolymer meets the following relationship: Tg (° C.)≤[0.625(° C./wt %)XC−55° C.], where Tg is the glass transition temperature of the interpolymer, and XC is the wt % crystallinity of the interpolymer.

A composition comprising an ethylene/C5-C10 alpha-olefin/non-conjugated polyene interpolymer, wherein the interpolymer meets the following relationship:
- Tg (° C.)≤[0.625(° C./wt %)XC−55° C.], where Tg is the glass transition temperature of the interpolymer, and XC is the wt % crystallinity of the interpolymer;
- and
- wherein the interpolymer meets the following relationship:
- Mw (g/mol)>{1097.8[(g/mol)/MV]*MV+87939(g/mol)}, where Mw is the weight average molecular weight of the interpolymer, and MV is the Mooney Viscosity (ML1+4, 125° C.) of the interpolymer;
- and
- wherein the non-conjugated polyene of the interpolymer is 5-ethylidene-2-norbornene (ENB) or 5-vinyl-2-norbornene (VNB).
A composition comprising a first composition that comprises a first ethylene/C5-C10 alpha-olefin/non-conjugated polyene interpolymer, and a second ethylene/C5-C10 alpha-olefin/non-conjugated polyene interpolymer;
- and wherein the first composition meets the following relationship:
- TgFC (° C.)≤0.625(° C./wt %)XCFC−55° C., where TgFC is the glass transition temperature of the first composition, and XCFC is the wt % crystallinity of the first composition;
- wherein the first ethylene/C5-C10 alpha-olefin/non-conjugated polyene interpolymer meets the following relationship:
- Mw (g/mol)>{1097.8[(g/mol)/MV]*MV+87939(g/mol)}, where Mw is the weight average molecular weight of the interpolymer, and MV is the Mooney Viscosity (ML1+4, 125° C.) of the interpolymer;
- and
- wherein the non-conjugated polyene of the first ethylene/C5-C10 alpha-olefin/non-conjugated polyene interpolymer is 5-ethylidene-2-norbornene (ENB) or 5-vinyl-2-norbornene (VNB).
