Claims3
The hydrolyzate of:
- ##STR20##
The hydrolyzate of:
- ##STR21##
The process of producing urea substituted silicon compounds which comprises reacting ammonia with the isocyanato groups of an isocyanatoorganosilicon compound having the formula:
- ##EQU5## wherein R.sup.5 is a divalent alkylene radical of at least 3 carbon atoms and which separates the isocyanato group from silicon by at least three sequential carbon atoms;
- R.sup.1 is a monovalent organic grop bonded to silicon by a carbon to silicon bond, selected from the group consisting of alkyl, cycloalkyl, aryl, alkaryl, aralkyl, alkenyl, alkadienyl, cycloalkenyl, haloalkyl, halocycloalkyl, cyanoalkyl, cyanoaryl, cyanocycloalkyl, carboxyalkyl, carboxyaryl, carboxycycloalkyl, isocyanatoaryl, isocyanatocycloalkyl, alkyl, carboxyalky, aryl carboxyalkyl, hydroxyalkyl, hydroxy(polyalkyleneoxy)alkyl, alkenoxyloxyalkyl, epoxyalkyl, epoxy alkyloxyalkyl, aminoaryl and aminoalkyl;
- each R.sup.2 is hydrogen or R.sup.1 ;
- R.sup.3 is a hydrolyzable or condensible radical, selected from the group consisting of hydroxyl, alkoxy, acyloxy, aryloxy, amino and haloalkoxy;
- R.sup.4 is a member selected from the group consisting of hydrogen, alkyl, aryl and acyl;
- m is 0 or 1;
- a is 0, 1 or 2;
- b is 0, 1, 2 or 3;
- o is 1;
- p is equal to 3-a when m is 0, and when m is 1, p is 0;
- and q is 0 when p is equal to 3-a and q is 0 or a positive number when m is 1.
