Rezumat:

A DSC and TGA study of linear polydicyclopentadiene (L-PDCPD) shows that the thermal behaviour of this polymer is characterized by an endothermic and two exothermic processes. In previous work it was demonstrated that the endothermic process is a glass transition and the second exotherm represents the thermo-oxidation of the polymer. In this work the first exothermic process is shown to be a possible thermal polymerization of the double bonds in the polymer chains.
