    摘要: The invention relates to polymer compositions useful as thermoplastic elastomers for extrusion, calendering, blow molding, thermoforming, and foam processing, and to articles made therefrom. Such improved melt strength thermoplastic elastomers include a blend of propylenic resin (A) and ethylenic elastomer (B), wherein the (A) resin is partially branched and/or the (B) elastomer is partially crosslinked by the addition of multifunctional acrylic monomer (C) containing at least three acrylate groups.
