    摘要: The subject invention is directed to polymer compositions which comprise a homogeneous ethylene/&agr;-olefin interpolymer, a wax and a nucleating agent, wherein the nucleating agent is provided in an effective amount such that the percent elongation at break of the polymer composition is at least about fifty percent greater than the percent elongation at break of a comparative composition which lacks the nucleating agent. The polymer compositions of the invention will find utility in applications r equiring high elongation at break, while maintaining a high onset of crystallization temperature, such as in the high-speed coating of fabrics, carpet backing, floor tile and sheeting, and adhesives.
