Abstract: A process to form a rheology modified composition, the process comprising applying radiation, and optionally heat, to a composition that comprises at least the following component: a) an olefin-based polymer comprising a total unsaturation ?0.20 /1000 C; and wherein the radiation is applied using an electron beam (e-beam) at a dosage selected from 0.1 MRad to 1.5 MRad; and wherein component a is selected from a telechelic polyolefin of the formula A1L1L2A2, an unsaturated polyolefin of the formula A1L1, or an ethylene/alpha-olefin interpolymer. A process to form a rheology modified composition, the process comprising applying heat, and optionally radiation, to a composition that comprises at least the following components: a) an olefin-based polymer, as described above, comprising a total unsaturation ?0.20/1000 C; b) from 1.0 to 100 ppm of a peroxide, based on the weight of the composition.

Abstract: A body part including a surface having a fluid flow thereover. The body part also includes flocking coupled to at least a portion of the surface that adjusts an aerodynamic characteristic relative to the surface that is devoid of the flocking.
