A method for calculatingglass transition point of plasticized polymers




Polimery 1981, No 3, 79



DOI: dx.doi.org/10.14314/polimery.1981.079

Summary

It has been found that the theoretical calculation of glasstransition point basing on the additivity rule of the free volume of polymerand of plasticizer gives results, which poorly agree with the experimentaldata. A new method for calculating has been proposed which uses the geometricalshape of the experimental and theoretical dependence of the glass transitionpoint on plasticizer content. The method has been verified on the examples ofpoly(vinylchloride) and polystyrene.
