A composition comprising a polymer selected from a polyolefin, a polyamide or mixture thereof, in admixture with an acrylic polymer additive, wherein: the shear viscosity of the composition is less than the shear viscosity of the same composition not containing the acrylic polymer; or, the extensional viscosity of the composition is less than the extensional viscosity of the same composition not containing the acrylic polymer additive; or, both of the shear viscosity and extensional viscosity of the composition is less than the shear viscosity and extensional viscosity of the same composition not containing the acrylic polymer addictive,when measured at an identical applied specific shear rate in the range of 5000 s
