Polymerization of 4-(N-Alkylanilino)-2-(amino or anilino)-6-isopropenyl-1, 3, 5-triazine

Abstract

New isopropenyl-1, 3, 5-triazines, e. g., 2-(amino or anilino)-4-(N-methyl-, ethyl- or butylanilino)-6-isopropenyl-1, 3, 5-triazines [1]-[5] were prepared. The homopolymerization of thesme monomaenrs and cropolmerizations with syrene, nethmyl methacrylate and mathylate (M₁) were carried out using azobisisobutyronitrile, as an initiator. The copolymerization parameters (r₁ r₂ Q₂ and e₂) were determined for these monomers. Thermal polymerization of these monomers was studied by differential scanning calorimetry (DSC). The ceiling temperature (T) and the heat of polymerization (ΔH_p) were obtained from DSC data, These ΔH_p and T_e values are in good agreement with those measured by the equilibrium monomer concentration determined by isothermal DSC. These monomers form ed glassy state when rapid cooled after melting. Some discussion was made, about the glassy state of the polymer-monomer system.
