Abstract
The present disclosure relates to an oil extended ethylene alpha-olefin composition including an olefin oligomer and an ethylene copolymer; where the olefin oligomer has a Number Average Molecular Weight of greater than about 200 g/mole; where the composition has a Shear Thinning Ratio of greater than about 100, a Phase Angle of less than about 45 degrees, a Mooney Large Viscosity (1+4@125° C.) of greater than about 40 Mooney units, and a Mooney Large Relaxation Area of greater than about 500 Mooney unit seconds.
Claims6
An oil extended ethylene alpha-olefin copolymer composition, comprising:
- extender oil comprising a portion of an olefin oligomer;
- and
- ethylene copolymer, wherein the ethylene copolymer incorporates another portion of the olefin oligomer;
- wherein the olefin oligomer is a propylene homo-oligomer or propylene co-oligomer, and wherein the olefin oligomer has a Mn of 200 g/mole to 15,000 g/mole;
- and
- wherein the composition has a Shear Thinning Ratio of greater than 100, a Phase Angle of less than 45 degrees in a complex shear modulus range of 50,000 Pa to 1,000,000 Pa, a Mooney Large Viscosity (1+4@125° C.) of greater than 40 Mooney units, and a Mooney Large Relaxation Area of greater than 500 Mooney unit·seconds.
