FIELD: chemistry.
SUBSTANCE: oxo-decomposing additive for polyolefins includes metal carboxylates or mixtures of metal carboxylates deposited on an inert support; the metal carboxylates used are, for example, 2-ethylhexanoates of zinc or zirconium. The inert support used can be calcium carbonate.
EFFECT: oxo-decomposing additive is capable of initiating oxidative breakdown of polyolefin chains in small concentrations.
