Abstract
A polymer blend foam having smooth skin and/or an open-cell content of at least 20 volume percent, a crosslinked gel content of no greater than 10 percent, a minimum cross-sectional area of at least 1000 mm.sup.2, and a density of no greater than 250 kg/m.sup.3. The blend includes (A) a substantially random interpolymer having polymerized therein (1) a vinyl or vinylidene aromatic monomer and/or a sterically hindered aliphatic or cycloaliphatic vinyl or vinylidene monomer, and (2) one or more of ethylene and a C.sub.3-20 aliphatic .alpha.-olefin; and (B) an olefin polymer based on one or more of ethylene, C.sub.3-20 aliphatic .alpha.-olefins, and C.sub.3-20 aliphatic .alpha.-olefins containing polar groups. The olefin polymer (B) lacks any of the vinyl or vinylidene aromatic monomers found in (A).
