Preparations of reaction products obtained from epoxides, fatty amines and reaction products which contain carboxyl groups, process for their manufacture and their use

Reaction products of epoxides, fatty amines and reaction products which contain carboxyl groups, which are

• 1. reaction products of
• a. an epoxide which contains in each molecule at least two epoxide groups and which is a polyglycidyl ether of 2,2-bis-(4'-hydroxyphenyl)-propane,
• b. a fatty amine containing 12 to 24 carbon atoms,
• c. a reaction product which contains carboxyl groups and is obtained from
• c.sub.1. a trihydric to hexahydric aliphatic alochol,
• c.sub.2. 1,2-propylene oxide, and
• c.sub.3. an aliphatic saturated dicarboxylic acid of 2 to 14 carbon atoms, an ethylenically unsaturated aliphatic dicarboxylic acid of 4 to 10 carbon atoms, a monocyclic or bicyclic aromatic dicarboxylic acid of 8 to 12 carbon atoms;
• or anhydrides thereof,
• and wherein the mole ration of (c.sub.1), (c.sub.2) and (c.sub.3) in (c) is 1:2 to 110:2 to 6;
• and optionally,
• d. an epihalohydrin, glycerol dichlorohyrin, acrylic acid, methylolacrylic acid, butylacrylate or acrylonitrile;
• wherein the reaction products (1) contain, per epoxide group equivalent of component (a), 0.1 to 0.7 amino group equivalent of component (b), 0.2 to 1.5 acid equivalents of component (c), and optionally 0.1 to 0.7 moles of component (d);
• and
• 2. an alkyl ether of a methylolaminotriazine aminoplast precondensate, and wherein the reaction products contain 5 to 70 percent by weight of component (2), relative to reaction products (1), and wherein (1) and (2) are present as a mixture, reaction product of (1) and (2), or both.

A process for the manufacture of reaction products of epoxides, fatty amines and reaction products which contain carboxyl groups, wherein

• 1. the ingredients
• a. an epoxide which contains in each molecule at least two epoxide groups and which is a polyglycidyl ether of 2,2-bis-(4'-hydroxyphenyl)-propane,
• b. a fatty amine containing 12 to 24 carbon atoms,
• c. a reaction product which contains carboxyl groups and is obtained from
• c.sub.1. a trihydric to hexahydric aliphatic alcohol,
• c.sub.2. 1,2-propylene oxide, and
• c3. an aliphatic saturated dicarboxylic acid of 2 to 14 carbon atoms, an ethylenically unsaturated aliphatic dicarboxylic acid of 4 to 10 carbon atoms, a monocyclic or bicyclic aromatic dicarboxylic acid of 8 to 12 carbon atoms;
• or anhydrides thereof,
• and wherein the mole ratio of (c.sub.1), (c.sub.2) and (c.sub.3) in (c) is 1:2 to 110:2 to 6;
• and optionally,
• d. an epihalohydrin, glycerol dichlorohydrin, acrylic acid, methylolacrylic acid, butylacrylate or acrylonitrile;
• wherein the ingredients (1) contain, per epoxide group equivalent of component (a), 0.1 to 0.7 amino group equivalent of component (b), 0.2 to 1.5 acid equivalents of component (c), and optionally 0.1 to 0.7 moles of component (d);
• and
• 2. an alkyl ether of a methylolaminotriazine aminoplast precondensate, and wherein the reaction products contain 5 to 70 percent by weight of component (2), relative to ingredients (1), are reacted in an organic solvent at temperatures of 80.degree. to 120.degree. C, or ingredients (1) alone are so reacted and the reaction product thereof mixed with component (2), or (1) and a portion of component (2) are so reacted and the reaction product thereof mixed with the remainder of component (2).
