Elastic Nonwoven Materials Comprising Propylene-Based and Ethylene-Based Polymers |
摘要 |
The present invention relates to elastic nonwoven materials comprising an elastic layer formed from a polymer blend comprising a propylene-based polymer and a minor amount of an ethylene-based polymer. The propylene-based polymer may comprise from about 75 to about 95 wt % propylene and from about 5 to about 25 wt % ethylene and/or a C4-C12 α-olefin, and may have a triad tacticity greater than about 90% and a heat of fusion less than about 75 J/g. The ethylene-based polymer may comprise from about 65 to about 100 wt % ethylene and from 0 to about 35 wt % of one or more C3-C12 α-olefins. |
