1. A process for preparing silylated organic polymers which comprises reacting a polymeric organic acid containing at least one acid group per molecule which is obtained from the polymerization of an organic acid having aliphatic unsaturation with a silylated aminofunctional polyether at a temperature of from -10°

  • C. to 200°

    C., in which the silylated aminofunctional polyether has the formula;

    ##STR20## wherein R is a radical selected from the group consisting of;

    ##STR21## R1 is selected from the class consisting of hydrogen, a monovalent hydrocarbon radical and a silicon containing radical selected from the group consisting of;

    ##STR22## and when R is ##STR23## A is an anionic silicon containing radical selected from the group consisting of;

    ##STR24## and when R is ##STR25## then A is selected from the group consisting of hydrogen, a monovalent hydrocarbon radical, and a silicon containing radical selected from the group consisting of;

    ##STR26## R2 is a divalent radical, R3 is a monovalent hydrocarbon radical having from 1 to 18 carbon atoms, R4 is a divalent hydrocarbon radical selected from the group consisting of (CH2)y, CH═

    CH or a cyclic hydrocarbon radical selected from the group consisting of C6 H4, C6 H8, C6 H10 and C10 H6, R5 is selected from the group consisting of hydrogen and a monovalent hydrocarbon radical, with the proviso that at least one A or R1 is a silicone containing radical, a is a number of from 0 to 4, e is 0, 1, 2 or 3, n is a number of from 2 to 4, x is a number of from 1 to 600 and y is a number of from 0 to 16.
