A process for the preparation of new polytriazine derivatives, useful as stabilizers to increase the stability to light of a synthetic polymer, of the general formula: ** (Formula) ** where R1 is selected from linear or branched C2 to C18 alkylene, C5 to C18 cycloalkylene, C6 to C18 arylene, and C7 to C18 aralkylene; R2 is selected from hydrogen, chlorine, bromine, -OH, straight or branched C1 to C18 alkyl, C5 to C18 cycloalkyl, substituted or unsubstituted C6 to C18 aryl, C7 to C18 aralkyl, a piperidyl radical of formula (II). |
