Calculations of phase equilibria for polymer blends
Živný, Antonín
Methods of calculations of phase equilibria in polymer blends with specific interactions are analyzed on the basis of the quasichemical Barker theory. Particularly, numerical solution of the equation of the spinodal and subsequent construction of curves of phase coexistence in these systems are performed.

Kinetics of polymer crystallization
Kratochvíl, Jaroslav ; Sikora, Antonín
Kinetics of three steps of complex crystallization of poly(N-methyldodecano-12-lactam) were studied by DCS using an Avrami model. Mechanism of respective isothermal steps involves mixed heterogeneous/homogeneous nucleation (primary melt crystallization) or missing nucleation phase (additional crystallization and recrystallization) followed by two-dimensional growth.
