Some new vinyl monomers with an amino-s-triazinyl group were synthesized. 2,4-Amino- and substituted amino-6-vinyl-s-triazines were synthesized by the reaction of the substituted biguanides with acrylyl chloride, while 2-amino-4-substituted amino-6-isopropenyl-s-triazines were prepared from the substituted biguanides with methyl methacrylate. It has been found that vinyl-s-triazines thermally polymerized immediately after melting and gave insoluble polymers. Polymers with amino-s-triazinyl groups in the side chain were obtained by the radical polymerization of some vinyl- and isopropenyl-s-triazines. The copolymerization of these monomers with styrene has been investigated in dimethyl sulfoxide using α,α′-azobisisobutyronitrile as an initiator. The monomer reactivity ratios were determined, and the Q and e values for these vinyl-s-triazines were calculated. Some discussions are presented.
