Nickel stabilizers for synthetic polymers

New complexes of nickel salts of hydroxybenzoic acids are stabilizers for polymers. The complexes are prepared by reacting a nickel benzoate with a corresponding alcohol.

Piperidine derivatives

A composition comprising an organic material and, as stabiliser, a compound having the formula SPC1 And salts thereof, wherein R1 and R2 are the same or different and each is an alkyl residue having from 1 to 12 carbon atoms or R1 and R2, together with the carbon atom to which they are bound, form a cycloalkyl residue having from 5 to 12 carbon atoms in the ring, Y is O, hydrogen, a straight or branched alkyl residue having from 1 to 20 carbon atoms, an alkenyl or alkynyl residue having from 3 to 12 carbon atoms, an aralkyl residue having from 7 to 12 carbon atoms or a group having the formula EQU1 wherein R is hydrogen, or a methyl or phenyl residue and R3 is hydrogen or a straight- or branched chain alkyl residue having from 1 to 12 carbon atoms.
