  • Low migratory photoinitiators for oxygen-scavenging compositions
    Patent number: 6464896
    Abstract: An improved composition and a method of scavenging oxygen using said composition which comprise oxidizable organic compounds, transition metal catalysts in combination with certain photoinitiators is disclosed. The method comprises initiating scavenging by exposing the composition to UV radiation. The present composition uses certain defined benzophenone derivatives which maintain effectiveness of photoinitiation while providing reduced migration of the photoinitiator from the resin matrix.

  • Methods and compositions for improved initiation of oxygen scavenging
    Patent number: 5811027
    Abstract: An improved method of initiating oxygen scavenging by compositions which comprise compounding oxidizable organic compounds and transition metal catalysts to form a composition suitable for forming into films or articles for packaging of oxygen sensitive products is disclosed. The method requires the addition of small amounts of a base to the oxygen scavenging composition as it is being compounded to improve the initiation properties and subjecting the film or article formed from the composition to actinic or electron beam radiation.
