Compositions containing a chlorine-containing polymer and at least one cyanoacetyl-urea derivative (I). Compositions containing a chlorine-containing polymer and at least one compound of formula (I): X = oxygen or sulfur; R = 2-22C acyloxyalkyl or 1-12C alkyl (optionally with 1-3 in-chain oxygen atoms and/or 1-3 hydroxyl substituents), 3-8C alkenyl, 5-8C cycloalkyl, 7-10C phenylalkyl or alkylphenyl, phenyl or naphthyl (all aromatic groups optionally substituted with OH, 1-12C alkyl or 1-4C alkoxy); R1 = H or a group as listed for R An Independent claim is also included for a method of stabilizing chlorine-containing polymers by incorporating (I). |
