Journal ArticleDOI
Prediction of the glass transition temperature of polymers
TL;DR: In this article, a method for predicting the glass transition temperature of polymers from the chemical structure was proposed, which uses increments for constitutional molecule groups and the found increments appear to correlate with the increments to the molar cohesion energy.
Journal ArticleDOI
Newtonian shear viscosity of polymeric melts
TL;DR: In this article, a new relationship has been found for the Newtonian viscosity of polymeric melts as a function of temperature and of chemical structure of the polymer unit, expressed graphically.
Journal ArticleDOI
Prediction of polymer densities
TL;DR: In this paper, a method is proposed for predicting the density of a linear, amorphous polymer based on the additivity of group increments for the molar volume of a polymer unit.
