Abstract:
1. An article comprising: (A) a frothed foam produced from a dispersion comprising: a catalytic linear multi-block olefin interpolymer that is a linear ethylene/α-olefin multi-block copolymer with at least 50 mole percent ethylene and having a Mw/Mn from 1.7 to 3.5, a melting point, Tm, in degrees Celsius, and density, d, in grams/cubic centimeter, wherein at least one dispersing agent comprising a polar polyolefin; wherein the catalytic linear multi-block olefin interpolymer comprises at least one hard segment and at least one soft segment; and the dispersion is dispersed in acrylonitrile monomer; (B) microcavities on at least one surface of the foam; and (C) the frothed foam has a compression set at 85° C., 20 minutes, at a pressure of 0.1 psig of less than 45 percent.
