摘要： A method for isomerization of lower polymers and copolymers of butadiene which is characterized in that the nonconjugated double bonds in said polymers and copolymers can be isomerized to conjugated double bonds by treating said polymer and copolymers at a temperature of 0 to 200*C in the presence of a catalyst comprising a dispersion of alkali metal and a diamine compound having active hydrogen, thereby polymers or copolymers with high reactivity and useful as paint vehicles, thermosetting materials, adhesives, rubber compounding materials and intermediates for various synthetic reactions, can be obtained.

摘要： A process is disclosed for the preparation of 5alkylidenenorbornene-2 for use as an important component of EPDM rubber. This product is obtained by the isomerization of 5alkenylnorbornene-2 which is accelerated by the catalytic action of certain complexes. These complexes are formed by combining organic alkalimetal compounds with alkylene diamines.

摘要： A process is disclosed for the preparation of 5alkylidenenorbornene-2 for use as an important component of EPDM rubber. This product is obtained by the isomerization of 5alkenylnorbornene-2 which is carried out in the presence of a composite catalyst having increased activity and tending to suppress the formation of undesirable side products. The composite catalyst is essentially comprised of a cyclopentadienyl cobalt compound, an organometallic compound and an activating agent, and has been found peculiarly effective in the isomerization reaction.
