抄録

The postpolymerization of 2-amino-4-N-methylanilino-6-isopropenyl-1, 3, 5-triazine (AMIT) irradiated in glassy-state with γ-ray of 60Co at -78°C was investigated. The DSC of AMIT irradiated in glassy-state showed a glass-transition temperature at 16°C and an exothermic peak due to polymerization at temperature near 41°C. This fact shows that the active species are trapped in the glass without causing polymerization until the glass-transition temperature is reached. The post-polymerization at 30-110°C of samples irradiated at -78°C gave polymers in saturated yields which depend on the polymerization temperature. It is shown by the measurement of ESR spectra and Gordon-Taylor's plot that a cause of the saturation of the polymer yield is not the disappearance of the active species but the glass formation of the polymer and monomer mixture during the postpolymerization.
