  • Publication number: 20140364573
    Abstract: The invention relates to a high-molecular-weight, linear, neodymium-catalysed polybutadiene having a high proportion, >95%, of cis-1,4 units having a low proportion, <1%, of 1,2-vinyl content, and also having a small molar-mass-polydispersity index (MPI), characterized in that Mooney viscosity (ML1+4 100° C.) of the polybutadiene is from 70 to 90 and The molar-mass-polydispersity index of the polybutadiene is smaller than 10.
