In 2016,Chu, Hualei; Song, Yuanqing; Li, Jiehua; Luo, Feng; Tan, Hong; Huang, Guangsu; Fu, Qiang published 《A novel phosphatidylcholine-modified polyisoprene: synthesis and characterization》.Colloid and Polymer Science published the findings.Application In Synthesis of tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate The information in the text is summarized as follows:
Polyisoprene (PI) is the main component of natural rubber. To imitate natural rubber and understand the function of phospholipid in natural rubber, a novel phosphatidylcholine (PC)-modified polyisoprene (PI-pc) was synthesized using a PC and a com. PI. The PI is firstly brominated by N-bromosuccinimide, and then, di-Et malonate is introduced as a branch chain of PI. In sequence, the PC is imported into the branch chain of PI via condensation of the activated ester terminals in di-Et malonate and the amino terminals in PC to obtain the desired product PI-pc. The bulk structure of the prepared PI-pc is carefully characterized with NMR spectra (1H and 31P NMR), Fourier transform IR spectroscopy (FT-IR), gel permeation chromatograph (GPC), and differential scanning calorimetry (DSC). The introduction of PC to the branch chain of PI increases the mol. weight and also the glass transition (Tg) of the PI. The increment of Tgs and melting enthalpy for the PI-pcs from both solution and emulsion indicates that the attached PC is beneficial to the self-assembly of PI chains and thus promotes the crystallization Our present work provides a new method for importing PC to PI to imitate natural rubber, and also, the results could be a footstone for us to explore the effect of phospholipid on the property of natural rubber. The results came from multiple reactions, including the reaction of tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate(cas: 139115-91-6Application In Synthesis of tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate)
tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate(cas: 139115-91-6) belongs to ethers.The C-O bonds that comprise simple ethers are strong. Application In Synthesis of tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate They are unreactive toward all but the strongest bases. Although generally of low chemical reactivity, they are more reactive than alkanes.
