CA 2588236

Polyester compositions are disclosed that include polyester polymers or copolymers having incorporated therein metallic molybdenum particles that improve the reheat properties of the compositions. Processes for making such compositions are also disclosed. The molybdenum particles may be incorporated in the polyester by melt compounding, or may be added at any stage of the polymerization, such as during the melt-phase of the polymerization. A range of particle sizes may be used, as well as a range of particle size distributions. The polyester compositions are suitable for use in packaging made from processes in which a reheat step is desirable.

La présente invention a trait à des compositions à base de polyester comportant des polymères ou des copolymères de polyester incorporant des particules de molybdène métalliques qui améliorent les propriétés de réchauffe des compositions. L'invention a également trait à des procédés pour la fabrication de telles compositions. Les particules de molybdène peuvent être incorporées dans le polyester par compoundage par fusion, ou peuvent être ajoutées à tout stade de polymérisation, telle que lors de la phase de fusion de la polymérisation. Une plage de tailles de particules peut être utilisée, ainsi qu'une plage de granulométries. Les compositions à base de polyester sont aptes à être utilisées dans des emballages obtenus par des procédés dans lesquels une étape de réchauffe est souhaitable.
