Patent ID: 7939618

Claim:
A continuous process for the preparation of organopolysiloxanes having chain-pendant aminoalkyl groups, comprising (i) reacting (A) linear, cyclic or branched organopolysiloxanes, with (B) aminoalkylsilanes which have an SiC-bonded, basic nitrogen-containing hydrocarbon radical and 2 or 3 hydrolyzable groups, or the partial or complete hydrolysis products thereof, (C) in the presence of at least one basic catalyst selected from the group consisting of alkali metal hydroxides, alkali metal alcoholates, and alkali metal siloxanolates, and, optionally, (D) chain-terminating reagents, and (ii) optionally, after the reaction (i) neutralizing the basic catalysts (C), with the proviso that compounds (A), (B) and, when used, (D) are reacted continuously in a reactor having a reaction space whose ratio of length to diameter is equal to or greater than four, and wherein the aminoalkyl groups are randomly distributed in the organopolysiloxane without block structures containing aminoalkyl groups.
