Structure of cis-polyisoprene from Lactarius mushrooms.

Antithrombin activity of a polyelectrolyte synthesized from cis-1,4-polyisoprene.

Dielectric Behavior of cis-Polyisoprene in Carbon Dioxide under High Pressure

Dielectric measurement was conducted for cis-polyisoprene (PIP) in carbon dioxide (CO2) at high pressures. CO2 is dissolved in PIP more with increasing pressure, and this dissolution is expected to affect the chain dynamics. In our experimental window, the PIP chains having type-A dipoles parallel along their backbone exhibited the dielectric dispersion reflecting their global motion. This disp...

Local Structure and Dynamics of Trans-polyisoprene oligomers

Monoand poly-disperse melts of oligomers (average length 10 monomers) of trans-1,4-polyisoprene are simulated in full atomistic detail. The force-field is developed by means of a mixture of ab initio quantum-chemistry and an automatic generation of empirical parameters. Comparisons to NMR and scattering experiments validate the model. The local reorientation dynamics shows that for C−H vectors ...

Solubility of Cis, Cis-Muconic Acid in Various Polar Solvents from 298.15 K to 348.15 K

The present work concerns with an investigation on the solubility of cis,cis-muconic acid dissolution in different polar solvents by characterizing and modeling the dissolution as a function of temperature. Water, ethanol, 2-propanol and acetic acid have been investigated as solvents in the range temperatures from a 298.15 to 348.15 K. Owing to the absence of cis,cis-muconic acid solubility...
