Abstract
This invention relates to a polyolefin blend composition comprising a polyolefin base polymer component and a functionalized polybutadiene component. The polyolefin blend exhibits both i) an increased melt flow and ii) an increased impact toughness and/or melt elasticity, as compared to the same composition without the functionalized polybutadiene. This invention also relates to a method of increasing the melt flow of a polyolefin and simultaneously increasing the impact toughness and/or the melt elasticity of the polyolefin by blending a polyolefin base polymer component and a functionalized polybutadiene component.
