New Advances in Chemical Research in 2021. HPLC of Formula: https://www.ambeed.com/products/10323-20-3.html, Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. 10323-20-3, Name is D-Arabinose, SMILES is O=C[C@@H](O)[C@H](O)[C@H](O)CO, belongs to dioxole compound. In a article, author is Yampolskii, YP, introduce new discover of the category.
The spin probe technique was systematically applied to study a family of high permeability and high free volume glassy polymers. Rotation correlation times tau(c) Or frequencies nu = 1/tau(c) of 2,2,6,6-tetramethylpyperidine-1-oxyl (TEMPO) were measured in amorphous teflons – random copolymers of tetrafluoroethylene and 2,2-bistrifluoromethyle-4,5-difluoro-1,3-dioxole, polyacetylenes and polynorbornenes. Polymers distinguished by unusually high, for the glassy state, permeability and free volume exhibit large rotational mobility of TEMPO. The correlation times correspond to fast rotation of the spin probe previously observed only in rubbery polymers, Correlations between the frequency nu and gas permeability and diffusion coefficients were observed. However, in some polymers, the spin probe’s rotation rate is also sensitive to side-chain local mobility, which does not affect translational diffusion coefficients of gas molecules in polymers.
