Continuous method for selective hydrogenation of ethylenic double bonds in polymers to give hydrogenated butadiene-styrene type copolymers for use, e.g. as paint binders and finishes for textiles, leather and paper

摘要

A method for the selective hydrogenation of ethylenic double bonds in polymers (P) by reaction with hydrogen in presence of a hydrogenation catalyst involves carrying out the reaction as a continuous process.
