ABSTRACT:
The present invention relates to polymeric composition of a first copolymer which includes at least one copolymer having at least one of Mw/Mn less than 2 and Mz/Mw less than 1.8; and a second copolymer having Mw/Mn greater than or equal to 2. The composition can be produced by preparing the first and second copolymers in different reactors and blending them. The blend can also be produced in a single reactor by initiating the reaction to prepare one copolymer, and adding additional reactants, or recycling the reaction mixture, during the reaction to produce the other copolymer.
