Theoretical description and simulation of polymer network formation
Premus, Jan ; Šomvársky, Ján (advisor) ; Dušek, Karel (referee)
One of methods for description of formation and structure of polymer ne- tworks is used in the work - combination of chemical kinetics and theory of branching processes (TVP) with correlations to neighbors. Main output of this work is computer program, whose purpose is setting up of rooted fragments of given size, differential equations for their concentrations and calculation of se- lected structural parameters using TVP. Gel points for systems formed by three and fourfunctional monomer and combination of two and threefunctional mono- mer were computated in this way. Chemical simulation of molecules was used as reference value. Larger correlation distance (larger size of fragments) led to more accurate results. Calculation of system parameters using TVP allowed study of gel parameters, concentrations of elastically active chains for all studied systems is shown in the work. 1
