Nitrogen-containing compounds
Abstract
Abstract Nitrogen-containing compounds comprising organo-silicon compounds containing at least one unit of the average general formula WHERE A is a group of the general formula IN WHICH R is an organic group free from olefinic unsaturation and having a valency of c + 1 and is selected from the group consisting of hydrocarbon groups having from three to 11 carbon atoms and groups consisting of carbon, hydrogen and oxygen, the latter in the form of ethereal linkages, having from six to 17 carbon atoms, R1 is selected from the group consisting of lower alkylene groups, R2 is selected from the group consisting of hydrogen, hydrocarbyl groups having not more than 12 carbon atoms and groups of the general formula (R3NRR4R5), R3 is a divalent radical attached at its extremities to two nitrogen atoms and is selected from the group consisting of hydrocarbon groups having not more than 12 carbon atoms, polyimino groups of the general formula ((R7NH)qR8) where R7 and R8 are alkylene groups having not more than four carbon atoms and q is a positive integer not greater than 100, and groups forming a heterocyclic structure with the amino nitrogen and R4 or with R2, R4 and the two nitrogen atoms attached to the extremities of R3, R4, when not a member of a heterocyclic structure, is selected from the group consisting of hydrogen, hydrocarbyl and hydroxy substituted hydrocarbyl groups and amino-alkyl and N-substituted amino-alkyl groups, R5 is selected from the group consisting of hydrogen, hydrocarbyl groups, hydroxy substituted hydrocarbyl groups, amino-alkyl and N-substituted amino-alkyl groups, c is 1, 2 or 3, B is a hydrocarbyl group free from aliphatic unsaturation, D is selected from the group consisting of hydrocarbyl groups and groups of the general formula B(OCnH2n)x, r is 1 or 2, s is 0, 1, 2, or 3, t is 0, 1, 2 or 3 and r + s + t is not greater than 4.
