    • Products prepared from polycarboxylic anhydrides and active hydrogen-functionalized elastomeric polymers, in particular polyoxyalkyleneamines, are suitable as builder components (prepolymers) for epoxy resin compositions. The reaction products are distinguished by having a plurality of carboxyl groups, but no imide groups, in each molecule. The reaction products may optionally be further reacted with epoxy resins and may optionally be formulated together with polymers having at least one glass transition temperature of -30°C or lower and epoxy-reactive groups and/or reaction products of said polymers with epoxy resins to provide resin systems useful in adhesives. Such adhesive formulations may additionally contain liquid and/or solid epoxy resins and/or hardeners and/or accelerators and/or fillers and/or and/or other impact-modifying components and/or rheology auxiliaries. Such is compositions exhibit excellent shelf life and are particularly suitable as impact-­resistant and peel-resistant adhesives in vehicle construction and in electronics. Particularly at very low temperatures, these adhesives exhibit very good impact and peel properties combined with very good corrosion resistance and aging resistance of the adhesive bond.

    • A novel water compatible curing agent for epoxy resins is provided. The curing agent can be made by (a) reacting at least one polyamine having at least 3 active amine hydrogen atoms per molecule and at least one epoxy resin having a functionality of at least 1.5 in an epoxy functionality equivalents to polyamine mole ratio of 0.9:1 to 1:10 thereby producing an amine-terminated intermediate; (b) reacting the amine-terminated intermediate with 0.5 to 25 weight percent, based on the amine-terminated intermediate, of an acid-terminated polyalkyleneglycol-containing compound having formulae (I), (II) and (III) wherein R is an alkyl, aryl, or arylalkyl group having 1 to 15 carbon atoms, X and Y are independently a hydrogen, methyl, or ethyl group with the provision that if X is methyl or ethyl, Y is hydrogen or if Y is methyl or ethyl, X is hydrogen, and n + m + o is a real number from 100 to 200, and n + o is at least 70 percent of n + m + o, and in a ratio of (I) to (II) by weight in the range of 100:0 to 0:100, and in a ratio of (I) to (III) by weight in the range of 100:0 to 0:100, and in a ratio of (II) to (III) by weight in the range of 100:0 to 0:100, until essentially all of the acid group is consumed. Such amine-terminated curing agent can also be capped with a monoepoxy. The curing agent can also be made (a) reacting at least one polyamine described above and an epoxy resin thereby producing an amine-terminated intermediate; (b) reacting the amine-terminated intermediate with a monoepoxy to provide a capped amine-terminated intermediate; then (c) reacting the capped amine-terminated intermediate with an acid-terminated polyalkyleneglycol-containing compound described above.
    • 提供了一种环氧树脂的新型水溶性固化剂。 固化剂可以通过以下方法制备:(a)使每分子具有至少3个活性胺氢原子的至少一种多胺与至少一种官能度至少为1.5的环氧官能度当量与多胺摩尔比为0.9:1的环氧官能度反应, 1至1:10,由此产生胺封端的中间体; (b)使胺封端的中间体与基于胺封端的中间体0.5至25重量%的具有式(I),(II)和(III)的酸封端的含聚亚烷基二醇的化合物反应,其中R 1 >是具有1至15个碳原子的烷基,芳基或芳基烷基,X和Y独立地是氢,甲基或乙基,条件是如果X是甲基或乙基,Y是氢或Y是甲基或 乙基,X为氢,n + m + o为100〜200的实数,n + o为n + m + o的70%以上,(I)〜(II) 重量比为100:0〜0:100,(I)〜(III)的比例为100:0〜0:100,以(II)〜(III )在100:0至0:100的范围内,直到基本上所有的酸基团被消耗。 这种胺封端的固化剂也可以用单环氧基封端。 固化剂也可制成(a)使至少一种上述多胺与环氧树脂反应,从而制得胺封端的中间体; (b)使胺封端的中间体与单环氧基反应以提供封端的胺封端的中间体; 然后(c)使封端的胺封端的中间体与上述酸封端的含聚亚烷基二醇的化合物反应。
