A cross-metathesized product mixture is prepared by contacting a metathesis catalyst under metathesis conditions with a composition comprising two or more chemically distinguishable ethylenically unsaturated polymers, at least one of said ethylenically unsaturated polymers (first polymer) having from 0.001 to 50 mole percent unsaturation and at least one other of said ethylenically unsaturated polymers (second polymer) being an amorphous polymer having a Tg less than 0° C. and having from 0.001 to 5 mole percent unsaturation.
