Abstract: One or more 1-butene polymers and uses thereof. The 1-butene polymer may be used as a viscosity modifier, flexibilizer, dispersing aid, and/or impact modifier for polymer compositions, such as those including polypropylene. The 1-butene polymer may also be used as a carrier for additives, such as fluorinated additives. Articles may be made that include the 1-butene polymer, polypropylene, and pigments.
