Novel Polybutadiene Diols for Thermoplastic Polyurethanes
Krasol® polybutadiene diols are anionically polymerized products characterized by very narrow molecular weight distribution, linear structure of polymer chains and the absence of species with functionality higher than 0.2. These unique features make them suitable as hydrophobic polyol components for use in thermoplastic polyurethanes (TPUs). Various TPU formulations were developed using polybut...
متن کاملMolecular 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 کاملMathematical Model of Novel COVID-19 and Its Transmission Dynamics
In this paper, we formulated a dynamical model of COVID-19 to describe the transmission dynamics of the disease. The well possedness of the formulated model equations was proved. Both local and global stability of the disease free equilibrium and endemic equilibrium point of the model equation was established using basic reproduction number. The results show that, if the basic reproduction numb...
متن کاملAromatic ionomers with superacid groups.
Aromatic polymers containing perfluorosulfonic acid groups show well-developed and interconnected ionic clusters, and thus high proton conductivity at wide humidity range.
متن کاملA molecular-dynamics simulation study of dielectric relaxation in a 1,4-polybutadiene melt
We have carried out atomistic molecular dynamics simulations of a melt of 1,4-poly~butadiene! from temperatures well above the experimentally observed merging of the primary a process and secondary b process down to temperatures approaching the experimentally observed bifurcation temperature. The relaxation strength and maximum loss frequency and its temperature dependence for the combined a-b ...
