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).

全丙烯酸超弹性体：易于合成和出色的机械性能†

全丙烯酸多接枝共聚物，聚（丙烯酸丁酯）-g-聚（甲基丙烯酸甲酯），使用简便的接枝方法合成，表现出断裂伸长率（> 1700％）和应变恢复性能，远远超过任何商用丙烯酸（迄今为止，约有500％）和苯乙烯（约1000％）三嵌段共聚物。使用仲丁基锂/ N-异丙基-4-乙烯基苄胺（仲）对甲基丙烯酸甲酯（MMA）进行单批阴离子聚合-BuLi / PVBA）引发系统可提供定量收率，较短的反应时间并使用简单的合成程序即可获得的PMMA大分子单体。这些新型的全丙烯酸超级弹性体和简单的合成方法极大地扩展了全丙烯酸热塑性弹性体（TPE）的潜在应用范围。
