RELATIONSHIP BETWEEN GLASS TRANSITION TEMPARETURE (Tg) AND MOLECULAR PARAMETERS OF POLYMERS II. Effect of molecular weight on Tg
The theoretical dependency of the glass transition temperature (Tg) on the degree of polymerization DP is deduced from the theory of the glass transition proposed in the previous paper:The theory agrees well with the experimental data taken from the literature for polystyrene
poly (vinyl chloride)
poly (a-methyl styrene)
poly (dimethyl siloxane) and poly (methyl methacrylate) with various tacticities. The theory leads directly to the relationship between the parameter Kg of the equation (Tg= Tg - Kg/Mn) and the molecular parameters. The agreement between the theoretical predictions and experimental measurments of Kg has been found to be satisfacory for a number of polymers.
