Abstract: Although polyolefin elastomers are widely employed commodity polymers, there are shortcomings of this class of polymers for certain applications. For example, the rheological properties of some polyolefin elastomers may be insufficient to provide the green strength or low shear viscosity necessary to form stable foams, or to provide sufficient viscosity modification effects when present in a solvent. Cationomeric modification of polyolefin elastomers may alleviate these difficulties. Such polyolefin elastomers may feature a random cationomeric polyolefin copolymer comprising at least a first monomer and a second monomer, in which the first monomer is a neutral monomer and the second monomer has a side chain bearing a cationic moiety. The polyolefin elastomers may be present in foamed polyolefin compositions comprising a gas component and/or in liquid compositions comprising a solvent in which the polyolefin elastomer is dissolved.
