Abstract:

This invention is directed to a process for the preparation of a crosslinker composition, comprising the steps of providing a mixture of an aliphatic alcohol A having at least one hydroxyl group and from 1 to 10 carbon atoms, with at least one multifunctional aldehyde C having at least two aldehyde groups —CHO to form a mixture AC, heating the mixture AC to convert at least a part of the multifunctional aldehyde C to its hemiacetal or to its acetal to form a mixture (AC)′, adding to the mixture (AC)′ least one cyclic urea U or the educts to produce the said cyclic urea U in situ, which cyclic urea U has at least one unsubstituted >NH group, and reacting the mixture thus obtained to form a chemical bond between the nitrogen atom of the at least one unsubstituted >NH group of the at least one cyclic urea U5 and the carbon atom of the least one aldehyde group —CHO of the multifunctional aldehyde C, and coating compositions comprising the said crosslinker composition.

International Classification:

C07D25148

US Classification:

544204

Abstract:

Provided is a novel carbamate functional 1,3,5-triazine of the general formula ##STR1## wherein Z' is selected from the group consisting of hydrogen, hydrocarbyl, and a group represented by the formula NHQ', each Q' is independently selected from the group consisting of a hydrocarbyl, a hydrocarbyloxy hydrocarbyl and a group represented by the formula COOY, with the proviso that at least two of the Q' groups are COOY, and each Y is independently selected from the group consisting of a hydrocarbyl group and a hydrocarbyloxy hydrocarbyl ether group, with the proviso that at least one Y group is a hydrocarbyloxy hydrocarbyl ether group. These carbamate functional 1,3,5-triazines find use, for example, as crosslinkers or reactive modifiers in curable compositions.

C07D24142
C07D25148
C07D25154

US Classification:

544194

Abstract:

The present invention relates generally to carboxylated amino-1,3,5-triazines and the preparation thereof via carboxylation of amino-1,3,5-triazines with carbon dioxide and a base. These carboxylated amino-1,3,5-triazines find use, for example, as intermediates in the production of other useful amino-1,3,5-triazine derivatives, and particularly carbamate and isocyanate functional 1,3,5-triazines. The present invention also relates to the preparation of such carbamate and isocyanate functional 1,3,5-triazines.

Abstract:

The present invention relates to carboxylated amino-1,3,5-triazines represented by the formula: ##STR1## wherein Z and Z. sup. 1 are independently selected from the group consisting of hydrogen, a hydrocarbyl, a hydrocarbyloxy and a group represented by the formula --N(Q). sub. 2 ; each Q is independently selected from the group consisting of hydrogen, a hydrocarbyl and a group Y, with the proviso that no more than one Q in each --N(Q. sub. 2) is Y; and Y is selected from the group consisting of a carboxyl group and a carboxylate salt group. These carboxylated amino-1,3,5-triazines find use, for example, as intermediates in the production of other useful amino-1,3,5-triazine derivatives, particularly carbamate and isocyanate functional 1,3,5-triazines. The so-produced derivatives may find use as, for example, crosslinking agents in curable compositions.
