Abstract

In the experiments, glass transition temperatures for a series of high-1,4 linear and star-branched polyisoprenes have been measured by differential scanning calorimetry. The Fox-Fox relation for the linear polyisoprenes was found to be T//g equals T//g infinity minus 1. 76 multiplied by 10**4 M OVER BAR //n** minus **1. The influence of hydroxyl groups on T//g was also examined for low molecular weight ( less than 2. 2 multiplied by 10**4) polyisoprenes.
