  • Publication number: 20190309487
    Abstract: Embodiments of the present disclosure are directed to stretched filaments comprising a non-functionalized polyolefin and at least one functionalized polymer. The functionalized polymer is a propylene-based plastomer or elastomer having one or more functional groups grafted on the propylene-based plastomer or elastomer. The one or more functional groups is selected from the group consisting of amine groups and imide groups. The at least one functionalized polymer has a DSC melting point from 100° C. to 130° C. When the stretched filament is stretched to a stretch ratio of 5, the stretched filament has a tenacity greater than 0.
