SAUERSTOFFENTFERNENDE ZUSAMMENSETZUNG ZUR ANWENDUNG BEI NIEDRIGEN TEMPERATUREN
摘要
<p>Improved compositions for scavenging oxygen are disclosed. These materials, characterized by low degree crystallinity and a glass transition temperature of lower than -15 DEG C., have high oxygen scavenging rates at low temperatures. The composition comprises an ethylenically unsaturated hydrocarbon and a transition metal salt catalyst and can be incorporated into various types of layers. It is preferable that the composition be incorporated into layers of multilayered articles used for packaging oxygen-sensitive products such as food products.</p>
