ABSTRACT:
An aminomethylation reaction is disclosed wherein polymeric polyamines are produced. Polymeric polyolefins such as polybutadiene, secondary amines, and synthesis gas are reacted in the presence of a catalyst system comprising a ruthenium-containing compound, a rhodium-containing compound, a sterically hindered phosphine and a solvent. Preferred polybutadiene feedstocks are those with a predominance of internal rather than pendant vinylic olefin groups and particularly those polymers containing both the 1,2-polybutadiene and 1,4-polybutadiene units.
