Definitions

  • Fig. 1 is a graph illustrating loss of elonga ⁇ tion at break as a function of time in a plastic film product including the composition of the pre ⁇ - ent invention.
  • composition of the present invention may be formed in any of the following manners.
  • the compo ⁇ sition may be added directly at the final production stage by the manufacturer, formed in a concentrate and supplied to the manufacturer to be added to the base resin or formed with the base resin and supplied to the manufacturer ready for use.
  • the first transition metal component preferably comprises an iron compound generally having the for ⁇ mula X-Fe, where X represents one or more ligands.
  • the compound may additionally be coupled to a fur ⁇ ther ligand Y.
  • Fe may designate iron in any known valancy.
  • the ligand X may be an inorganic or organic acid radical or likewise another ligand bonded in a complex.
  • suitable ligands X include OH-, C1-, Br-, I-, oxalate-, H-citrate-, NO- , N-.- EDTA or a carbonyl, nitrosyl or porphyrin radical.
  • Suitable ligands Y include carboxylic acid ions of aromatic or aliphatic monocarboxylic acid or of dicarboxylic acids, the aliphatic carboxylic acid preferably having 10 to 20 carbon atoms.
  • Ligand Y serves in general to increase the solubility of the compound X-Fe in the polymer.
  • the iron compound more preferably is comprised of iron stearate pres ⁇ ent in the final concentration of the present inven ⁇ tion in an amount from about 0.01 weight percent to about 0.5 weight percent, and more preferably in an amount from about 0.1 weight percent to about 0.3 weight percent. It is understood that the ranges listed herein are for purposes of illustration.
  • thermoplastic composition of the present invention formed in a concentrate wherein the compositional ranges of the various components are by weight percent of the total concentrate.
  • thermoplastic composition of the present invention formed in a concentrate wherein the compositional ranges of the various components are by weight percent of the total concentrate.
