Articles of manufacture containing an extrusion-foamed polymeric composition. The extrusion-foamed polymeric composition contains an ethylene-based polymer and an olefin-based elastomer. The extrusion-foamed polymeric composition can be prepared from a foamable polymeric composition containing the ethylene-based polymer, the olefin-based elastomer, a nucleating agent, and a blowing agent. The extrusion-foamed polymeric composition can be prepared using an extrusion foaming process.

An ion exchange membrane has multiple layers of ionic polymers which each contain substantially different chemical compositions. i.e. varying side chain lengths, varying backbone chemistries or varying ionic functionality. Utilizing completely different chemistries has utility in many applications such as fuel cells where for example, one layer can help reduce fuel crossover through the membrane. Or one layer can impart substantial hydrophobicity to the electrode formulation. Or one layer can selectively diffuse a reactant while excluding others. Also, one chemistry may allow for impartation of significant mechanical properties or chemical resistance to another more ionically conductive ionomer. The ion exchange membrane may include at least two layers with substantially different chemical properties.

The present disclosure provides compositions and products formed therefrom. In particular, the disclosure provides elastomeric latex articles, such as gloves and condoms, that can exhibit a desired combination of properties that can be correlated to suitable strength and softness.
