The preparation of a new monomer, 4, 6-diamino-2-vinyl-s-triazine has been described. The homopolymerization and CO-polymerization of this monomer with methyl vinyl ketone, 2-N, N-dimethylamino-4-vinylpyrimidine and 4-vinylpyrimidine by radical catalysis is described. The homopolymerization and copolymerization with styrene of these latter two monomers have also been carried out. The introduction of another nitrogen into the ring when ...
