For diisopropyl ether, a comparative assessment of the accuracy of determining the density and viscosity is carried out using the method of classical molecular dynamics using three potentials. The accuracy of determining the viscosity coefficients when using equilibrium and non-equilibrium calculation ...
The glass transition temperature (t(g)) of cyclic polystyrene was measured by differential scanning calorimetry. there was a marked difference in the glass transition behaviour between cyclic and linear polystyrene. in the low molecular weight region (m(n) 10(5)). combining the results of specifi...

New catalysts for the synthesis of highly reactive polyisobutylene: chloroaluminate imidazole-based ionic liquids in the presence of diisopropyl ether The use of [emim]Cl-AlCl3 in combination with diisopropyl ether allowed us to synthesize highly reactive polyisobutylene with an exceptionally high exo-ol...
The conversion and selectivity for MTO reaction were calculated on CH2 basis. Dimethyl ether was considered as reactant due to the fast equilibrium between methanol and dimethyl ether.Data availability All data supporting the findings of this study are available within the article and its ...
The assembly of oligopeptide and polypeptide molecules can reconstruct various ordered advanced structures through intermolecular interactions to achieve protein-like biofunction. Here, we develop a “molecular velcro”-inspired peptide and gelatin co-as
4). EMB and C160 exhibited most structural similarity, namely, presence of a macrocyclic ring containing ether functional group, both the structures possess tetrahydopyran in the side chains. The pesticide derivates C107 and C165 does not possess any noticeable similarities with EMB other than the...
By heating at above the melting point and/or glass transition point of the polycondensate and adding an aromatic dicyanate; or adding a mixture comprising an aromatic dicyanate and a polyfunctional co
sufficiently comminuted to pass a 20 mesh screen. After the reaction subsided, the resulting polymer product was tested for molecular weight by the viscosity method. A series of samples of the purified isobutylene were polymerized in the same manner, except that small amounts of isopropyl ether ...
Blends of carbonate and monovinylidene aromatic copolymers containing selected low molecular weight halogenated epoxy compounds, in combination with tetrafluoroethylene polymers, are shown to have sur
