Polymers of a conjugated dime, an unsaturated nitrile and a vinyl aromatic compound are selectively hydrogenated to reduce ethylenic carbon-carbon double bonds, without also reducing nitrile groups and aromatic carbon-carbon double bonds, preferably using a rhodium-containing compound as catalyst. The hydrogenated polymers are novel and display valuable properties.
