ABSTRACT:
Polymers or oligometic compounds of the general formula ##STR1## in which X, X.sup.a and X.sup.b are an ester, amide or cyano group, Y, Y.sup.a and Y.sup.b are --O-- or --NR.sup.10 --, R.sup.1, R.sup.1a and R.sup.1b are a group which contains a polyalkylpiperidine radical, and R.sup.1a can also be alkyl, and R.sup.3, R.sup.3a and R.sup.3b are alkylene, alkenylene, arylene-dialkylene, cycloalkylene-dialkylene or monooxa-alkylene or polyoxa-alkylene, can be prepared by the polycondensation of malonic acid esters or amides or cyanoacetic acid esters or amides with difunctional compounds, preferably dihalogen compounds, in the presence of bases. The products obtained have a molecular weight of 800 to 20,000 and are outstanding light stabilizers for organic polymers.
