Title (EN) CYCLO-DEPOLYMERISATION OF POLYBUTADIENE
(FR) CYCLO-DÉPOLYMÉRISATION DU POLYBUTADIÈNE
Abstract:
(EN) In general the present invention concerns a method for cyclo-depolymerisation of polybutadiene to large macrocycles by metathesis catalysts. More specifically this invention relates to a novel process for the degradation by olefin metathesis, forming unsaturated macrocycles, prepared by metathesis of a 1,3-butadiene polymer, such as polybutadiene, or of polymers containing such 1,3-butadiene polymer and of rubbers or rubber compositions or rubber nanocomposites, for instance comprising butadiene.
(FR) La présente invention concerne en général un procédé de cyclo-dépolymérisation du polybutadiène en gros macrocycles par des catalyseurs de métathèse. Plus spécifiquement, la présente invention concerne un nouveau procédé pour la dégradation par métathèse oléfinique, formant des macrocycles insaturés, préparés par métathèse d'un polymère de 1,3-butadiène tel que le polybutadiène, ou de polymères contenant un tel polymère de 1,3-butadiène et de caoutchoucs ou de compositions de caoutchouc ou de nanocomposites de caoutchouc, par exemple comprenant du butadiène.
