ABSTRACT:
The present invention is an elastomeric polyolefin terpolymer comprising about 5 to 25 weight percent ethylene units, from greater than about 5 to about 40 weight percent hexene units, and about 35 to less than about 90 weight percent propylene units, wherein the total weight percent of monomer units equals 100 percent. The high molecular weight terpolymer is amorphous, is elastomeric, has a melt flow rate of about 0.01 to 500 grams per 10 minutes and has a tensile set of about 65 to 120 percent, according to ASTM D-412.
