ABSTRACT New piperidine derivatives of 1,3,5-triazine which are useful for improving the resistance of synthetic polymers to light, heat and oxidation. The new compounds are comprises in the general formula Image (I) where : R1, R2, which may be equal or different, each represent one atom of hydrogen, a linear or branched alkyl containing 1 to 18 C, a cyclo- alkyl containing 5 to 18 C, an unsubstituted or substituted aryl containing 6 to 18 C, an arylalkyl containing 7 to 18 C, or a pipe- ridinearadical of formula (II): Image (II) in which R3, R4, R6, R7, which may be equal or different, each re- present an alkyl containing 1 to 6 C, and R5 represents H, O, an alkyl of 1 to 12 C, an alkenyl or alkinyl of 2 to 12 C; X, Y, which may be equal or different, each represent -O-, -S-, -N-R8-, where R8 is H or a linear or branched alkyl containing : to 18 C, a cycloalkyl containing 5 to 18 C, a substituted or unsubstituted aryl, containing 6 to 18 C, an arylalkyl contain- ing 5 to 18 C, or a piperidine radical of formula (II); the radicals R1-X-, R2-Y- may also represent radicals of nitroge- nated heterocyclic compounds of 5 to 8 terms joined to the triazino ring by an arom of nitrogen of said radical; n is a whole number between 7 and 2000; Z represents a n-valent radical obtained by eliminating n atoms of active hydrogen fromelinear or branched polyamines containing at least 7 primary and/or secondary amino groups, for example the po lyamines characterized by repetitive units of type ; Image (III) or Image (IV) or Image (V) or Image (VI) or Image (VI) in which R9, R10, R11, which may be equal or different, each repre- sent an alkylene of 2 to 12 C, a cycloalkylene of 5 to 12 C, an aryl lene of 6 to 12 C, an arylalkylene of 7 to 12 C, or a Image -3- radical, R12 is hydrogen, a linear or branched alkyl of 1 to 12 C, a cycloalkyl of S to 12 C, a substituted or unsubstituted aryl of 6 to 12 C, an arylalkyl of 7 to 12 C, and m is zero or l; in formula (1) the condition that the radicals R1-X or R2-Y- contain at least one piperidine radical of formula (II) must be satisfied.
