Compositions may include an EVA copolymer produced from ethylene, vinyl acetate, and one or more polar comonomers, wherein at least one of the one or more polar comonomers include an amine moiety. Methods may include preparing a polymer composition by adding ethylene, vinyl acetate and one or more polar comonomers to a reactor or extruder, wherein at least one of the one or more polar comonomers include an amine moiety; and reacting the ethylene, vinyl acetate and one or more comonomers to produce the polymer composition. Compositions may include an adhesive film composition that include at least one layer including a polymer produced from ethylene, vinyl acetate, and one or more polar comonomers, wherein at least one of the one or more polar comonomers include an amine moiety.

Modified ethylene vinyl acetate compositions, polymer blends and films made therefrom

Foamed compositions that include: one or more foamable polymers; one or more ionomeric additives; and wherein the foam composition exhibits shrinkage as determined at 70&#xb0; C.*1 h according to the PFI method between 0.1 and 3.5%. Methods may include preparing a polymer composition by combining one or more foamable polymers and one or more ionomeric additives in a mixer to produce the polymer composition; and foaming the polymer composition to generate a polymer foam exhibiting shrinkage as determined at 70&#xb0; C.*1 h according to the PFI method of between 0.1 and 3.5%.
