Abstract MOIETY, Z being bonded to the nitrogen atom by a C-N bond; R'' is independently selected from the group consisting of the hydrogen atom, lower alkyl radical or a heterocyclic organic compound containing the nitrogen atom as a ring member; M IS AN INTEGER OF 1 OR 2; R'''' is the hydrogen atom or a lower alkyl radical; and Y is an acid anion; are polymerized with vinylic monomers to produce organosilicon-containing polymers having utility as elastomers and coating compositions. GROUPS OR NITROGEN IN THE FORM OF GROUPS; Z is a divalent organic radical having a double bond conjugated with the IN WHICH Q is a divalent hydrocarbon radical or a divalent hydrocarbon radical containing oxygen in the form of Organosilicon compounds of the formula
