On characteristic points of the plasticization function of biopolymers

Characteristic points of the plasticization function (temperatures and concentrations) are determined in ranges from the offset of the Zhurkov plasticization mechanism to the UCST of a plasticizer-polymer system and from the LCST of the plasticizer-polymer system to the point of the plasticizer freezing out from a biopolymer. Expressions for the correcting parameter of the Gordon-Taylor equation in these ranges which are related to characteristic temperatures and concentrations are obtained. Simplified expressions for characteristic concentrations are found.
