Polybutadiene with epoxy groups, is new. The polybutadiene comprises (a) but-1-en-2,3-diyl, (b) (E)-but-2-en-1,4-diyl and (c) (Z)-but-2-en-1,4-diyl monomer units derived from 1,3-butadiene. The amount of (a) to the total amount of monomer units (a)-(c) present in polybutadiene is 10-60 mole.%, preferably 15-30 mole.%. The sum of the amounts of (b) and (c) to the total amount of monomer units (a)-(c) present in polybutadiene is 40-90 mole.%. Independent claims are also included for: (1) preparing the polybutadiene; (2) a composition comprising the polybutadiene, which is prepared by the above mentioned method, at least one hardener, and optionally at least one epoxy resin; and (3) curing the composition. |
