The present invention provides an additive for thermoplastic polymer foams which provide for enlarged cell size or with decreased density with minimal impact on the thermal mechanical properties of the thermoplastic foam. The additive is an essentially block copolymer blowing agent compatibilizer. Including the additive in a thermoplastic foaming composition comprised of a thermoplastic polymer resin and a physical blowing agent provides for the production of foam having enlarged cell size or with decreased density and minimal impact on the thermal mechanical properties of the thermoplastic foam. The block copolymer compatibilizer has at least a first block having at least one functionality compatible with the thermoplastic resin and at least one second block having a functionality compatible with the blowing agent.

L'invention porte sur un additif pour polymères thermoplastiques expansés qui donne un produit expansé à cellules plus larges ou de densité réduite, et dont les propriétés thermiques et mécaniques sont à peine affectées. L~additif est un compatibiliseur d~agent d~expansion essentiellement formé de copolymères blocs. L~adjonction à la mousse à expanser de l~additif, qui comprend une résine polymère thermoplastique et un agent d~expansion, provoque un élargissement des cellules et un abaissement de la densité. Le compatibiliseur comporte au moins un premier bloc dont au moins une fonction est compatible avec la résine thermoplastique, et au moins un deuxième bloc dont au moins une fonction est compatible avec l~agent d~expansion.
