Quantitative Simulations on Temperature-Dependent Lattice Thermal Capacity of Linear, Branched and Cyclic Polymers
Author(s): Valeri Ligatchev*
Effects of spatial confinement, and interactions among neighboring molecular fragments, as well as amendments in topological characteristics are taken into account explicitly at semi-empirical quantitative evaluations on temperature-dependent isochoric lattice thermal capacity of several one-dimensional (linear), branched and ‘cyclic’ polymeric macromolecules, in order to replicate compellingly their experimentally obtained temperature-dependent isobaric counterparts. Those experimental dependencies might exhibit ‘sublinear’, nearly-linear, and ‘super-linear’ enlargement(s) with the temperature within ‘moderate’ temperature ranges alongside with so-called ‘low-temperature anomalies’, which are persistently manifested in profound decline(s) in the lattice thermal capacities with the temperature diminishment below the ‘mo..
