All-acrylic superelastomers: facile synthesis and exceptional mechanical behavior

Author affiliations

Abstract

All-acrylic multigraft copolymers, poly(butyl acrylate)-g-poly(methyl methacrylate), synthesized using a facile grafting-through methodology, exhibit elongation at break (>1700%) and strain recovery behavior far exceeding those of any commercial acrylic (∼500%) and styrenic (∼1000%) triblock copolymers to date. One-batch anionic polymerization of methyl methacrylate (MMA) using the sec-butyl lithium/N-isopropyl-4-vinylbenzylamine (sec-BuLi/PVBA) initiation system gives PMMA macromonomers with quantitative yield, short reaction time, and using simple synthetic procedures. These new all-acrylic superelastomers and the simple synthetic approach greatly expand the range of potential applications of all-acrylic thermoplastic elastomers (TPEs).
