Abstract
Provided are blend compositions comprising a propylene-based elastomer and a polyalphaolefin. The blend compositions may be particularly useful in elastic film compositions, and especially useful as elastic film layers in nonwoven laminates. The film may comprise a blend of from about 0.5 to about 60 wt % of a polyalphaolefin and 40 to 99.5 wt % of a propylene-based elastomer. The film may comprise a blend of a propylene-base elastomer that comprises propylene and from 5 to 30 wt % of an α-olefin and a polyalphaolefin having a kinematic viscosity (KV) at 100° C. of from 3 to 3000 cSt.
