![]() Besides, the materials were also mechanically tough with an outstanding breaking strain of around 500% and a high tensile strength over 10 MPa. As a result, these block polymers exhibited excellent shape memory property (shape recovery ratio: 95%). The monomer selection as well as the design of molecular architecture facilitated microphase separation in the prepared polymers, leading to two networks formed by the vitrified PMMA domain and the supramolecular interactions from the AMPS component, respectively. ![]() A series of diblock polymers, polymethylmethacrylate-b-poly(butylacrylate-co-2-acrylamido-2-methyl-1-propanesulfonic acid) (PMMA-b-P(BA-co-AMPS)) with varying molecular weights and compositions were conveniently synthesized. ![]() Shape memory thermoplastics are an important class of engineering polymers with smart characteristics.
