On September 14, 2021, Zhang, Jian; Li, Siyu; Wang, Zhigang; Liu, Peng; Zhao, Youliang published an article.Application of 6038-19-3 The title of the article was Multitunable Thermoresponsive and Aggregation Behaviors of Linear and Cyclic Polyacrylamide Copolymers Comprising Heterofunctional Y Junctions. And the article contained the following:
The incorporation of asym. Y junctions into thermoresponsive polymers allows access to hierarchical self-assembly, and self-assembly of cyclic polymers can further amplify the topol. effect. At present, systematic insights into the influence of Y junctions on physicochem. properties remain at the early stage. A diversity of linear and cyclic polyacrylamide copolymers with substituent-variable Y junctions are designed to reveal the effects of topol., chain length, composition, concentration, and temperature With the increasing size of substituents, copolymer aqueous solutions gradually shift from dual upper and lower critical solution temperatures (UCST/LCST) to a single LCST until the lack of phase transition. The LCST can be elevated by introduction of a cyclic architecture, longer polymer chain, and smaller substituent. Owing to the changes in degree of hydration of subunits, heat can induce sphere-vesicle-nanosheet-nanoribbon-sphere (linear copolymer) and sphere-nanosheet-nanoribbon (cyclic copolymer) transitions. In addition, the cyclization effect is also reflected in cooperative hydration of distinct subunits upon heating, higher ceiling temperatures to form stable lamellae, and more pronounced hysteresis of the turbidity curve upon cooling. This research using Y junction bearing thermoresponsive copolymers may provide a promising platform to achieve on-demand phase transitions and nanostructures. The experimental process involved the reaction of 3-Aminodihydrothiophen-2(3H)-one hydrochloride(cas: 6038-19-3).Application of 6038-19-3
