Abstract

Novel cationic amino resins having a weight average molecular weight of at least 400 and an amine value of 20 to 700 and processes for producing the same characterized (a) by subjecting to thermal polymerization an alicyclic conjugated polyene compound having an alicyclic ring of 5 to 7 carbon atoms and an ethylenically unsaturated amino compound at 170 to 300.degree. C.; (b) by subjecting to thermal polymerization an alicyclic conjugated polyene compound having an alicyclic ring of 5 to 7 carbon atoms and an .alpha.,.beta.-ethylenically unsaturated nitrile at 170 to 300.degree. C. to prepare a copolymer containing a nitrile group and hydrogenating the copolymer to reduce the nitrile group.
