Producing Polydicyclopentadiene from Lower-Grade Dicyclopentadiene

Polymer samples based on polydicyclopentadiene produced from Russian dicyclopentadiene are investigated by thermogravimetric analysis and differential scanning calorimetry. A second stage of polymerization—that is, heat treatment of the samples—is found to increase the degree of polymerization and improve the physicomechanical properties of the polydicyclopentadiene.
