Abstract
A method for increasing the melt strength of a polyolefin polymer composition is provided. The method includes mixing a first polyolefin composition derived from at least one olefin polymerization catalyst (a) and at least one olefin polymerization catalyst (b) with a second polyolefin composition derived from the at least one olefin polymerization catalyst (b) or from at least one olefin polymerization catalyst (c), and obtaining the polyolefin polymer composition.
