Summary:EMBODIMENTS OF THE INVENTION PROVIDE A CLASS OF ETHYLENE/?-OLEFIN BLOCK INTERPOLYMERS. THE ETHYLENE/?-OLEFIN INTERPOLYMERS ARE CHARACTERIZED BY AN AVERAGE BLOCK INDEX, ABI, WHICH IS GREATER THAN ZERO AND UP TO ABOUT 1.0 AND A MOLECULAR WEIGHT DISTRIBUTION, M?/Mn., GREATER THAN ABOUT 1.3. PREFERABLY, THE BLOCK INDEX IS FROM ABOUT 0.2 TO ABOUT 1. IN ADDITION OR ALTERNATIVELY, THE BLOCK ETHYLENE/?-OLEFIN INTERPOLYMER IS CHARACTERIZED BY HAVING AT LEAST ONE FRACTION OBTAINED BY TEMPERATURE RISING ELUTION FRACTIONATION ("TREF"), WHEREIN THE FRACTION HAS A BLOCK INDEX GREATER THAN ABOUT 0.3 AND UP TO ABOUT 1.0 AND THE ETHYLENE/?-OLEFIN INTERPOLYMER HAS A MOLECULAR WEIGHT DISTRIBUTION, M?/Mn GREATER THAN ABOUT 1.3.
