Zusammenfassung:The invention relates to a polymer blend prepared by the process of combining under polymerization conditions: (A) a first catalyst capable of producing a first crystalline polymer having an Mw of 100,000 or less, (B) a second catalyst capable of preparing a second amorphous polymer having an Mw of 100,000 or less and differing in chemical or physical properties from the first polymer under equivalent polymerization conditions, (C) a cocatalyst, activator, scavenger, or combination thereof, and (D) one or more olefins; wherein the polymer blend is formed in-situ, comprises crystalline polymer segments and amorphous polymer segments, and has an Mw of 100,000 or less.
