, (2008/06/13)
Malonates of the formula I STR1 in which R1 is hydrogen or C1 -C4 -alkyl, R2 is C1 -C12 -alkyl, C3 -C4 -alkenyl, benzyl or phenyl which is optionally substituted by C1 -C8 -alkyl or C1 -C8 -alkoxy, or is cyano, R3 is C1 -C12 -alkyl, C3 -C4 -alkenyl or benzyl and X denotes hydrogen, oxyl, C1 -C12 -alkyl, C3 -C6 -alkenyl, C3 -C4 -alkinyl, C2 -C21 -alkoxyalkyl, C7 -C8 -aralkyl, 2,3-epoxypropyl, an aliphatic acyl group with 1-4 C atoms or one of the groups --CH2 COOR4, --CH2 --CH(R5)--OR6, --COOR7 or --CONHR7, in which R4 is C1 -C8 -alkyl, C3 -C6 -alkenyl, phenyl, C7 -C8 -aralkyl or cyclohexyl and R5 is hydrogen, methyl or phenyl and R6 denotes hydrogen or an aliphatic or aromatic, araliphatic or alicyclic acyl group with 1-18 C atoms, in which the aromatic part can optionally be substituted by chlorine, C1 -C4 -alkyl or C1 -C8 -alkoxy and/or by hydroxyl, and R7 is C1 -C12 -alkyl, cyclohexyl, phenyl or benzyl as stabilizer for organic polymers.
