Abstract: An organic polymer comprising an organic polymer fragment and at least one S-alkylsilyl hydrocarbonthioate group or at least one S-alkylstannyl hydrocarbonthioate group bonded to the backbone of the organic polymer fragment through a C—Si covalent bond and their methods or production are provided. The organic polymer backbone can be derived from the anionic polymerization of monomers containing C—C unsaturation. The silicon or tin atom can be further bonded to two alkoxy groups, two hydrocarbon groups or to one alkoxy group and one hydrocarbon group.

Abstract: A method of stabilizing imino-functional silane involving adding thereto at least one Brønsted-Lowry base to inhibit, suppress or prevent the addition reactions of the imino-functional silane with itself to form a imino- and amino-functional silane and the subsequent deamination reactions to form conjugated carbon-carbon double bond-containing imino-functional silanes and stabilized imino-functional silanes containing the at least one Brønsted-Lowry base.
