Formula: C3H9IOSIn 2019 ,《Controlled synthesis of polymethylene-b-poly(ethylene glycol) as well as its crystallization and self-assembly behavior》 appeared in International Journal of Polymer Analysis and Characterization. The author of the article were Zhang, Yan; Zhou, Qihang; Liu, Yujian. The article conveys some information:
Polymethylene-b-poly(ethylene glycol) (PM-b-PEG) with different block length ratio was synthesized by a combination of polyhomologation and coupling reaction. The effect of hydrophilic and hydrophobic block length on the crystallization process and self-assembly behavior of PM-b-PEG was self-assembled were investigated. The results showed that with the increase of methylene units, the crystallization temperature of PM block raised from 54.59 °C to 70.93 °C gradually, while that of the PEG block reduced from 17.54 °C to 15.23 °C. In addition, the amphiphilic PM-b-PEG was self-assembled into star-like micelles in water, and its diameter extended from 98.2 nm to 151.9 nm as the block length of hydrophobic PM increased from 30 to 70. And the micelles also exhibit super stability when the concentration of copolymer precursor is 0.50 ∼ 0.90 mg/mL and the storage temperature lies in the range of 25 ∼ 60 °C. In the part of experimental materials, we found many familiar compounds, such as Trimethylsulfoxonium iodide(cas: 1774-47-6Formula: C3H9IOS)
Trimethylsulfoxonium iodide(cas: 1774-47-6) reacts with sodium hydride to prepare dimethyloxosulfonium methylide, which is used as a methylene-transfer reagent in synthetic chemistry. It is used to prepare ylide, which reacts with carbonyl compounds to get epoxides. Further, it reacts with alfa,beta-unsaturated esters to get cyclopropyl esters.Formula: C3H9IOS
