CONJUGATIVE EFFECT OF PYRIDAZINONE RING ON THE COPOLYMERIZABILITIES OF 3(2-SUBSTITUTED)6-METHYLPYRIDAZINONES WITH STYRENE
Radical copolymerizations of several pyridazinones (I–VI) with styrene (M1) have been carried out. It has been found that plots of log 1⁄r1, against both νc=o and νc=c in the pyridazinone ring gave straight lines, indicating that the reactivity of the double bond in the ring might be affected by the ring conjugation which involves the carbonyl group.
