Abstract
2-Octadecylamino-4-(N-octadecylanilino)-6-isopropenyl-1,3,5-triazine (2N18) and 2-dioctadecylamino-4-(N-octadecylanilino)-6-isopropenyl-1,3,5-triazine (3N18) were prepared from 2-amino-4-(N-octadecylanilino)-6-isopropenyl-1,3,5-triazine (N18) with octadecyl bromide in the presence of sodium hydride. In the polymerization of these monomers, the polymer yield decreased with increasing numbers of octadecyl groups due to decrease in ceiling temperature. Copolymerizations of these monomers with styrene and methyl methacrylate were carried out in benzene using 2,2′-azobisisobutyronitrile as an initiator, and monomer reactivity ratios (r1 and r2) were determined. The reactivity of these monomers decreased with increasing numbers of the octadecyl groups. The long alkyl side-chains of the resulting comb-like polymers could be crystallized. The degree of crystallinity and melting temperature of the side-chains for 2N18 and 3N18 polymers were higher than those for N18 polymers.
