Abstract
High molecular weight linear copolymers of ethylene and 1-50 mole percent linear .alpha.-olefins having from 10 to 100 carbon atoms are disclosed. The polymers have M.sub.w of 30,000-1,000,000, MWD of 2-4, a density of 0.85-0.95 g/cm.sup.3, and a high composition distribution breadth index. Also disclosed are a method for making the polymers with a cyclopentadienyl metallocene catalyst system, and adhesives, films, molded articles and other products made from the copolymers.
