Cyclo-depolymerisation of polybutadiene

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.
