Abstract:
A copolymer comprising 5 to 25% by weight of ethylene-derived units and 95 to 75% by weight of propylene-derived units, the copolymer having:(a) a melting point of less than 90Â° C.; (b) a relationship of elasticity to 500% tensile modulus such that Elasticity&lE;0.935M+12, where elasticity is in percent and M is the 500% tensile modulus in MPa; and (c) a relationship of flexural modulus to 500% tensile modulus such that Flexural Modulus&lE;4.2e0.27M+50, where flexural modulus is in MPa and M is the 500% tensile modulus in MPa.
