Abstract:
a method for producing (1) moldings from finely divided materials, wherein the finely divided material is mixed or impregnated with a heat-curable composition and the resultant mixture is shaped at temperatures above 120Â° C. or (2) consolidated sheetlike structures of fiber materials, wherein an unconsolidated sheetlike structure of fiber materials is first treated with a heat-curable composition and then heated at temperatures above 120Â° C., wherein the heat curable composition comprises:(A) at least one reaction product of i. at least one polycarboxylic acid of the formula I: â€ƒin which R is a hydrogen or a CH2COOH group, X is hydrogen, OH or NH2, but is OH or NH2 if Y is hydrogen, Y is hydrogen, OH or NH2 but is OH or NH2 is X is hydrogen, or X and Y together area &pgr; bond, and/or an anhydride of the polycarboxylic acid I ii. with ammonia and, if desired, iii. with primary amines and/or compounds containing at least two hydroxyl groups; and/or (B) a mixture of at least one polycarboxylic acid of the formula I and/or its anhydride and at least one substance which releases ammonia on heating and, if desired, primary amines and/or compounds containing at least two hydroxyl groups.
