| abstract |
The invention relates to a polybutadiene having epoxy groups, where the polybutadiene comprises the monomer units (A), (B) and (C), where the proportion of A in the entirety of the monomer units derived from 1,3-butadiene present in the polybutadiene is 10 to 60 mole percent, where the sum of the proportions of B and C in the entirety of the monomer units derived from 1,3-butadiene present in the polybutadiene is 40 to 90 mole percent, to a process for preparing the inventive polybutadiene and to a composition comprising the polybutadiene having epoxy groups. |
