HYDROGENATION OF DENE BASED POLYMER LATEX IN THE PRESENCE OF AN IN SITU SYNTHESIZED CATALYST

摘要

A technique of improving the hydrogenation reaction of diene based polymers present in aqueous suspension by in situ synthesizing the catalyst in the presence of a specific aliphatic alcohol is disclosed. The process allows the selective hydrogenation of the carbon carbon double bonds in the diene based polymers with a high degree of hydrogenation and short reactions times. The improved process eliminates the complicated catalyst synthesis operations so far necessary.
