Abstract: Embodiments of polymer blends may include a first polymer composition and a second polymer composition. The first polymer composition may include a polyolefin having a thermal transition temperature of at least 100° C. and a graftable monomer having at least one acid or anhydride functional group grafted onto the polyolefin. The second polymer composition may include an E/X/Y ethylene interpolymer, wherein E is an ethylene monomer and comprises greater than 50 wt. % of the interpolymer, X is an α,β-unsaturated C3-C8 carboxylic acid and comprises greater than 0 to 25 wt. % of the interpolymer, and Y is an optional comonomer comprising C1-C8 alkyl acrylate.

Abstract: Embodiments are directed to polymer compositions and foams including polymer compositions. Embodiments of the polymer composition may include at least 55 wt. %, based on the total weight of the polymer composition, of a polyolefin elastomer having an ethylene content of from greater than 50 wt. % to less than 80 wt. % and a cross-linkable blend comprising: (i) from 1 wt. % to 99 wt. %, based on the total weight of the cross-linkable blend, of an E/X/Y polymer and (ii) from 1 wt. % to 99 wt. %, based on the total weight of the cross-linkable blend, of an epoxycontaining polymer.
