Molecular Dynamics of a 1 , 4 - Polybutadiene Melt
We have made detailed comparison of the local and chain dynamics of a melt of 1,4-polybutadiene (PBD) as determined from experiment and molecular dynamics simulation at 353 K. The PBD was found to have a random microstructure consisting of 40% cis, 50% trans and 10% 1,2-vinyl units with a number average degree of polymerization = 25.4. Local (conformational) dynamics were studied via measu...
متن کاملThermal Properties and Three-Phase Structure of cis-1,4-Polybutadiene
The thermal properties of cis-1,4-polybutadiene (cis-PBD) were investigated in dependence of content of cis units and of linearity of the main chain. cis-PBD grades containing a fraction of cis-segments ranging from 93 to 98 %, and with linear or branched chains, were analyzed. Upon isothermal crystallization from the melt at -26 °C for 1 h, followed by cooling to below the glass transition tem...
متن کامل4-Aminopyridinium cis-2-carboxycyclohexane-1-carboxylate
In the structure of the title molecular salt, C(5)H(7)N(2) (+)·C(8)H(11)O(4) (-), the cis monoanions associate through short O-H⋯O hydrogen bonds in the carb-oxy-lic acid groups [graph set C(7)], forming zigzag chains which extend along the c axis. These are inter-linked through pyridinium and amine N-H⋯O hydrogen bonds, giving a three-dimensional network structure.
متن کاملcis-2-(4-Methoxyphenyl)-4-methyl-1,2-dihydronaphthalen-1-ol
The stereochemistry and regiochemistry of the title compound, C18H18O2, were determined by the X-ray analysis. There are two independent mol-ecules in the asymmetric unit in which the dihedral angles between the benzene rings are 88.31 (4) and 86.27 (4)°. The cyclo-hexene rings are in half-chair conformations. In the crystal, O-H⋯O hydrogen bonds link alternating types of mol-ecules into chains...
متن کاملInvestigation of the binding of cis / trans - [ MCl 4 ( 1
Overall binding affinity of sodium or indazolium cis/trans-[MCl4(1H-indazole)(NO)] (M = Ru, Os) complexes towards human serum albumin (HSA) and high molecular mass components of the blood serum was monitored by ultrafiltration. HSA was found to be mainly responsible for the binding of the studied ruthenium and osmium complexes. In other words, this protein can provide a depot for the compounds ...
