ABSTRACT:
Novel, rubbery copolymers of ethylene with at least one other .alpha.-alkene such as propylene, and a polyene such as 5-ethylidene norbornene-2, characterized by a differential scanning calorimetry thermogram maximum peak at a temperature between -7.degree. and +11.degree. C., are disclosed. These specific rubbery copolymers when one or more tackifiers are included therein, exhibit an unprecedentedly high tack and consequently provide for the first time EPDM-type compositions that have sufficient building tack for the manufacture of multi-ply articles such as tires.
