Synthesis and Porous Structure of Addition Polymer Based on Dicyclopentadiene

A simple two-stage scheme is proposed for the synthesis of a new porous polymeric material based on dicyclopentadiene, an industrial product and one of the most accessible derivatives of norbornene. The selective addition polymerization of dicyclopentadiene, a bifunctional monomer, proceeds via opening of only one endocyclic double bond and the subsequent hydrogenation of the synthesized product makes it possible to obtain a saturated polymeric material with a high specific surface area (425 m 2 /g). The porous structure of the hydrogenated addition polydicyclopentadiene is studied in comparison with a similar polymer before hydrogenation using low-temperature nitrogen adsorption/desorption and X-ray powder diffraction. It is shown that the polymeric material obtained has a high thermal stability.
