  • Thermoforming, scratch-resistant, low gloss compositions comprising interpolymers of ethylene/?-olefins
    Patent number: 9006380
    Abstract: This invention relates to polymer compositions comprising at least one ethylene/?-olefin interpolymer and a branched and/or high melt strength polypropylene, methods of making the polymer compositions, and molded, overmolded, extruded into profiles or thermoformed products made from the polymer compositions. The polymer compositions may have reduced post-thermoformed sheet and post extruded (profile) gloss properties and/or improved scratch-resistant properties.
    Type: Grant
