    摘要： A foaming composition is provided comprising a particulate ingredient having a plurality of internal voids containing entrapped supercritical fluid having a critical temperature of at least about 10° C. Additionally, a method is provided for preparing such a foaming composition. A supercritical fluid having a critical temperature of at least about 10° C. is contacted with a particulate ingredient having a glass transition temperature above ambient temperature at a temperature above the glass transition temperature of the particulate ingredient, wherein the particulate ingredient comprises a plurality of internal voids. The particulate ingredient is held at the temperature above the glass transition temperature of the particulate ingredient for a period of time effective to allow transfer of the supercritical fluid into the plurality of internal voids of the particulate ingredient. Subsequently, the temperature is reduced to below the glass transition temperature of the particulate ingredient, thereby entrapping at least a portion of the supercritical fluid in the plurality of internal voids of the particulate ingredient.

    摘要翻译： 提供了一种发泡组合物，其包含具有多个内部空隙的颗粒成分，所述内部空隙含有临界温度为至少约10℃的截留的超临界流体。另外，提供了制备这种发泡组合物的方法。 具有至少约10℃的临界温度的超临界流体在高于颗粒成分的玻璃化转变温度的温度下与玻璃化转变温度高于环境温度的颗粒成分接触，其中所述颗粒成分包括多个 内部空隙。 颗粒成分保持在高于颗粒成分的玻璃化转变温度的温度下一段有效时间，以允许超临界流体转移到颗粒成分的多个内部空隙中。 随后，将温度降低至低于颗粒成分的玻璃化转变温度，从而在颗粒成分的多个内部空隙中截留至少一部分超临界流体。
