Abstract
The invention relates to controllably degradable polymer compositions, especially suitable for making film products, comprising a vinyl polymer, and at least one first complex which is a non-ionic organosoluble antioxidant complex of a chain-breaking, peroxide-decomposing, metal ion deactivating or ultraviolet light stabilizing compound and of a metal such that the metal complex is a photoactivator and at least one second complex which is a non-ionic organosoluble ultraviolet light stabilizing complex of a metal such that the metal complex is a photostabilizer, the concentrations of the two complexes being co-ordinated to produce a desired embrittlement time for the composition. The first complex is an iron complex and the second a nickel complex or a cobalt complex.
