Silyl-substituted urea derivatives
Abstract
Abstract New organosilyl- and carbamate-modified urea derivatives have the formula IN WHICH R and R'' are monovalent hydrocarbon radicals, R'''' and R'''''' are hydrogen atoms or monovalent hydrocarbon radicals, Q'' is a bivalent hydrocarbon radical, Q is a monovalent to hexavalent hydrocarbon radical, a is 0, 1, 2 or 3, n is 2, 3 or 4, b is zero or an integer from 1 to 200, and c is the valency number of Q. These urea derivatives are prepared by reacting at a temperature of from -20* to 150* C an aminoalkyl-silane derivative of the formula WITH AN ISOCYANATE-MODIFIED CARBAMIC ACID ESTER OF THE FORMULA The products are to be used as priming agents imparting adhesion to synthetic resins on siliceous surfaces, as surfactants and as intermediates for organo-polysiloxane resins.
