Abstract
Described herein are propylene-based polymer compositions that comprise a reactor blend of a first polymer component and a second polymer component. The first polymer component has an ethylene content of from greater than 12 to less than 19 wt % ethylene, and the second polymer component has an ethylene content of from greater than 4 to less than 10 wt % ethylene. Preferably, the ethylene content of the first and second polymer components satisfy the formula:−1.7143+29.771≤≤−1.9167+37.25.The propylene-based polymer compositions are particularly useful for forming meltspun nonwoven compositions that exhibit a desirable balance of retractive force and permanent set.
