ACTIVATABLE POLYMER COMPOSITION COMPRISING AT LEAST TWO CARBOXYLIC ACIDS AS BLOWING AGENT

The invention relates to a curable volume expandable polymer composition comprising an organic acid component, wherein the organic acid component comprises a first organic acid, a second organic acid,and optionally one or more additional organic acids; wherein said polymer composition, when being heated to an activation of expansion temperature above room temperature, undergoes volume expansion.When the organic acid component is heated to the activation of expansion temperature, the first organic acid and/or the second organic acid and/or the optionally present one or more additional organicacids are de-carboxylated and thus release carbon dioxide. The polymer composition traps the thus released carbon dioxide thereby causing the polymer composition to undergo volume expansion. 本发明涉及包含有机酸组分的可固化、体积可膨胀的聚合物组合物，其中有机酸组分包含第一有机酸、第二有机酸和任选的一种或多种另外的有机酸；其中所述聚合物组合物在被加热至高于室温的膨胀活化温度时经历体积膨胀。当有机酸组分被加热至膨胀活化温度时，第一有机酸、和/或第二有机酸、和/或任选存在的一种或多种另外的有机酸脱去羧基，因而释放二氧化碳。聚合物组合物捕捉由此释放的二氧化碳，从而使聚合物组合物经历体积膨胀。
