Zusammenfassung:	Alkoxylated hydrophobes that include a poly(alkylene oxide) chain of at least 5 oxyalkylene units having a terminal secondary hydroxyl group or a terminal C1-8 hydrocarbyl group are effective internalmold release agents for epoxy resin moldings. The alkoxylated hydrophobe, when mixed with an epoxy resin, forms a mixture that is highly stable when heated to 80 to 100 DEG C and held at that temperature for a period of as much as 22 days. 包括具有至少5个氧化烯单元的聚(环氧烷)链的烷氧基化疏水物为用于环氧树脂模制品的有效内部脱模剂，所述烷氧基化疏水物具有末端仲羟基或末端C烃基。当与环氧树脂混合时，所述烷氧基化疏水物形成在加热至80至100℃时高度稳定并且在所述温度下保持长达22天的时段的混合物。
