Abstract Polymers or oligomeric compounds of the general formula Image in which X, Xa and Xb are an ester, amide or cyano group, y.ya and yb are -0- or -NR10-, R1, R1a and R1b are a group which contains a polyalkylpiperidine radical, and R1a can also be alkyl, and R3, R3a and R3b are alkylene, alkenylene, arylene-dialkylene, cycloalkylene-dialkylene or monooxa- alkylene or polyoxa-alkylene, can be prepared by the poly- condensation of malonic acid estersor amides or cyanoacetic acid esters or amides wlth difunctional compounds, prefer- ably dihalogen compounds, in the presence of bases. The products obtained have a molecular weight of 800 to 20,000 and are outstanding light stabilisers for organic polymers.
