    • Provided is a curable composition, which serves as an aqueous thermosetting binder for fiber substrates or composite materials, allows effective curing at a lower temperature in a shorter time, and causes no harmful side effects caused by emission of formaldehyde. The curable composition comprises: (i) at least one polyacid containing at least two carboxylic acid groups or anhydrides or salts thereof; (ii) optionally, at least one polyol containing at least two OH groups; and (iii) at least one reactive beta-hydroxyamide group-containing polyol represented by the following formula (I), which is a reaction product between lactone or other cyclic esters and alkanolamine, wherein the ratio of the equivalent number of the carboxylic acid groups or anhydrides or salts thereof to that of the OH groups is 1/0.01 to 1/3. In the formula 1, each of R and R" independently represents H, or a monovalent C1-C18 linear or branched alkyl group that may have one or two aryl or cycloalkyl groups, at least one OH, amine, thiol, amide, carboxyl or alkenyl group or a combination thereof; R' is a divalent C1-C5 alkylene group that may have an alkyl substituent; y is an integer of 1 or 2; and x is 0 or 1 so that x+y=2.
    • 提供作为纤维基材或复合材料的水性热固性粘合剂的固化性组合物,能够在较短时间内在较低温度下有效固化,并且不会引起由甲醛排放引起的有害副作用。 可固化组合物包含:(i)至少一种含有至少两个羧酸基团或其酸酐或其盐的多酸; (ii)任选的至少一种含有至少两个OH基团的多元醇; 和(iii)至少一种由下式(I)表示的反应性β-羟基酰胺基多元醇,其是内酯或其它环状酯与链烷醇胺之间的反应产物,其中羧酸基团的当量数 或其酸酐或其盐与OH基的酸酐或盐的比例为1 / 0.01至1/3。 在式1中,R和R“各自独立地表示H,或者可以具有一个或两个芳基或环烷基的一价C1-C18直链或支链烷基,至少一个OH,胺,硫醇,酰胺,羧基或 烯基或其组合; R'是可以具有烷基取代基的二价C1-C5亚烷基; y是1或2的整数; x是0或1,使得x + y = 2。
