    摘要: Composition based on thermoplastic polymers, especially .alpha.-olefine polymers, such as polyethylene or ethylene copolymers, to which have been added, to promote degradation, a biologically degradable substance, an iron compound possibly complex and soluble in the composition, an oxidizable substance having one or several double bonds, selected from fatty acids and/or fatty acid esters, as well a further possible compound of a transition metal with the exception of iron as a catalyst. Said compositions demonstrate a markedly improved degradation capability when exposed to heat and/or ultraviolet light and/or sunlight and/or when in conditions promoting decomposition.
