Abstract
Thermoplastic elastomer compositions comprising acrylic multigraft copolymers are described. The multigraft copolymers comprise a rubbery polyacrylate backbone and a plurality of randomly spaced glassy polyacrylate side chains. The multigraft copolymers can be prepared using a facile grafting through method that can provide copolymers with enhanced purity. The acrylic multigraft copolymers exhibit microphase separated morphologies and 'superelastomeric' properties, including an elongation at break, stress at break, and/or strain recovery behavior that exceeds that of conventional triblock copolymer polyacrylate thermoplastic elastomers.
