    • 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.
    • 本发明提供一种用于热塑性聚合物泡沫的添加剂,其提供增大的泡孔尺寸或具有降低的密度,同时对热塑性泡沫的热机械性能的影响最小。 添加剂是基本上是嵌段共聚物发泡剂增容剂。 将添加剂包括在由热塑性聚合物树脂和物理发泡剂组成的热塑性发泡组合物中,提供具有增大的泡孔尺寸或具有降低的密度和对热塑性泡沫的热机械性能影响最小的泡沫。 嵌段共聚物相容剂至少具有至少一种与热塑性树脂相容的功能的第一嵌段和至少一个具有与发泡剂相容的功能的第二嵌段。
