    • 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.
    • 低聚物和丁二烯共聚物异构化的方法,其特征在于所述聚合物和共聚物中的非共轭双键可以通过在0至200℃的温度存在下处理所述聚合物和共聚物而异构化成共轭双键 的催化剂,其包含碱金属和具有活性氢的二胺化合物的分散体,由此可以获得具有高反应性并可用作涂料载体的聚合物或共聚物,热固性材料,粘合剂,橡胶配混材料和用于各种合成反应的中间体。
