The effect of grafting density and side chain length on the conformation of PEG grafted bottlebrush polymers was written by Xiao, Lifen;Li, Jie;Peng, Gang;Huang, Geng. And the article was included in Reactive & Functional Polymers in 2020.Quality Control of (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol This article mentions the following:
PEG grafted polymers are a kind of promising materials, and widely applied in polymer electrolytes, lubricants, biotechnol. and biomedical science. While up to now, systematical researches of the relationship between architecture and conformation of PEG grafted polymers are very rare. Here, we efficiently and successfully prepared a series of PEG grafted polymers with different grafting d., and side chain length by combining ring-opening metathesis polymerization (ROMP) and Copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction, and then characterized the conformations of the synthesized bottlebrush polymers by AFM technique. The AFM images showed that all the polymers P(NB-alkyne)400-g-PEG with low grafting d. were spherical morphol., while the polymers P(NB-2alkyne)400-g-PEG and P(NB-4alkyne)394-g-PEG presented cylindrical morphol., which indicated that only grafting d. could determine the shape of the prepared PNB-g-PEG bottlebrush polymers. While, the side chain length could affect the size of prepared PEG grafted bottlebrush polymers. In the experiment, the researchers used many compounds, for example, (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol (cas: 100-79-8Quality Control of (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol).
(2,2-Dimethyl-1,3-dioxolan-4-yl)methanol (cas: 100-79-8) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Although benzodioxole is not particularly important, many related compounds containing the methylenedioxyphenyl group are bioactive, and thus are found in pesticides and pharmaceuticals.Quality Control of (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol
