Résumé

Polydicyclopentadiene (PDCPD) thermoset, as commonly prepared by ring-opening metathesis polymerization (ROMP), features excellent mechanical, thermal and anti-corrosion properties, but lacks ductility and toughness. In situ addition of 2 to 8 wt% of Styrene-Ethylene-Butylene-Styrene (SEBS) thermoplastic during material preparation slightly alters the stiffness while improving its toughness and ductility. Remarkably, 4wt% SEBS increases PDCPD glass transition temperature T g up to 165 °C (i.e. + 7 °C). Calorimetric analyses suggest that addition of SEBS, acting as a plasticizer during molding, reduces the polymerization time of DCPD. This result offers a simple method to adjust PDCPD impact properties and to increase its T g .
