SYNTHESIS AND FREE-RADICAL POLYMERIZATION OF TRIAZINYLSTYRENE DERIVATIVES

Reaction of 2,4-dichloro-6-p-vinylphenyl-1,3,5-triazine with nucleophi lic reagents such as diethylamine, ethanol, diethyleneglycol monomethy lether, and ethanthiol in the presence of a base in THF gave the corre sponding substituted compounds in moderate to high yields. The resulti ng monomers, which have two functional groups, polymerized readily in the presence of AIBN at 60 degrees C to afford the corresponding homop olymers. The copolymerization parameters of each monomer were calculat ed from their copolymerization with styrene. Q values of these monomer s were larger than that of styrene, indicating participation of the tr iazine ring to resonance of the monomers. On the other hand, e values of these monomers were approximately zero because of the electron-with drawing character of the triazinyl group.
