The glass transition in linear polymers

Abstract

It is suggested that polymeric materials undergo the glass transition when the energy contained in the scissoring modes of vibration of the polymer backbone becomes comparable with the van der Waals forces restraining the end of a vibrating segment. As the temperature is raised the vibrating segments gradually increase in length, causing large changes in the macroscopic properties. It is shown that for certain polymers the glass transition temperature may be calculated from first principles. The glass transition temperature depends upon molecular weight and the change in specific heat at this temperature may be quite accurately calculated.
