    摘要: 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.

    摘要: Polymer compositions comprising a vinyl polymer and a combination of at least two metal complexes wherein the complexing agent of the first complex is attached to the metal through oxygen and the metal is a transition metal, and the complexing agent of the second complex is attached to the metal through sulphur and the metal is a transition metal or a metal of group II or IV of the periodic table of the elements, wherein the molar ratio of the second metal complex to the first metal complex is 0.5 or less. A film obtained from such polymer compositions and its use agricultural processes are also claimed.
