Abstract
Abstract Triazine derivatives for use as light and heat stabilizers and for improving fatigue properties in rubber vulcanizates have the following composition: A 1,3,5-triazine derivative of the formula WHEREIN X is -SR6 or chlorine, and Y is or -SR7, R1, R2, R3 and R4 being hydrogen, alkyl of 1 to 18 carbon atoms, phenyl, allyl, or methallyl and wherein alkyl may be substituted by -OH, -OR5 (R5 being lower alkyl) or -CN and wherein R1 and R3 may also be Alpha -naphthyl or Beta -naphthyl with the provision that the R2 or R4 group which is attached to the same N must then be hydrogen; and wherein R6 and R7 are alkyl of 1 to 18 carbon atoms or a thioether group of the formula
