Abstract: A method includes providing a starting material having a Young's modulus (202). Second, from a plurality of possible modifiers, a modifier is identified and selected that has a Young's modulus comparable to or greater than that of the starting material and that, when blended with the starting material, creates a blend with a stable morphology (204). Third, the scratch resistance of the starting material is increased by blending the modifier with the starting material to form a blend (206). Alternatively, the scratch resistance of the stating material is maintained while the toughness of the starting material is increased by blending the modifier with the starting material to form a blend.

Abstract: A low stress relaxation elastomeric material comprises a block copolymer having an elasotmeric soft block portion and thermoplastic hard block portions, at least one vinylarene resin and mineral oil. The elasotmeric material may be used in a film comprising an elastomeric layer and at least one substantially less elastomeric skin layer. The skin layer comprises a thermoplastic polymer such as polyolefins. The film exhibits desired elastic and stress relaxation properties at body temperature. The film is useful in forming a macroscopically-expanded, three-dimensional elastomeric web.
