On March 14, 2022, Wang, Hui; Fliedel, Christophe; Manoury, Eric; Poli, Rinaldo published an article.Reference of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate) The title of the article was Core-crosslinked micelles with a poly-anionic poly(styrene sulfonate)-based outer shell made by RAFT polymerization. And the article contained the following:
Core-crosslinked micelles (CCMs) with a permanently charged anionic shell of sodium poly(styrene sulfonate) (PSS-Na+) chains were developed by a convergent three-step one-pot RAFT polymerization starting with 4-cyano-4-thiothiopropylsulfanyl pentanoic acid (CTPPA, R0-SC(S)SnPr) as chain transfer agent, which includes polymerization-induced self-assembly (PISA) in the second step. The final crosslinking step of the R0-(SS-Na+)x-b-Sty-SC(S)SnPr diblock chains was carried out with diethylene glycol dimethacrylate (DEGDMA), either diluted into styrene (DEGDMA/St = 10:90) or neat. The morphol. of the intermediate micelles and of the final CCM particles was studied by dynamic light scattering (DLS) and transmission electron microscopy (TEM) as a function of the relative degrees of polymerizations for the shell, core, and crosslinking blocks. Conformational instability was observed for the aqueous dispersions of the diblock micelles, especially with the shorter PSt blocks, yielding equilibrium with single chains and large agglomerates. However, crosslinking led to well-defined CCMs with narrow size distributions for the optimized polymer compositions The DLS anal. in a compatibilizing 60:40 THF/H2O solvent mixture demonstrates that the final step of the polymer synthesis has quant. crosslinked all diblock arms. The experimental process involved the reaction of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)(cas: 2358-84-1).Reference of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)
