<p>Novel silyated organic polymers and processes for their preparation are provided herein. Such silylated organic polymers are obtained from the reaction of a silylated organic polymer and a cyclic organopolysiloxane, the silylated organic polymer being obtained from the reaction of a silane of the formula where R is a monovalent hydrocarbon radical, X is selected from the class consisting of halogen, acyloxy radicals, hydrocarbonoxy radicals, sulfato radicals, phosphato radicals and perchlorato radicals, a is a number of from 1 to 4 and b is a number of from 1 to 3, with a carbanion containing organic polymer, the carbanion containing polymer being obtained from the polymerization of an unsaturated organic monomer having carbon-to-carbon double bonds in the presence of a carbanion forming catalyst. These silylated organic polymers are useful since they provide silylated organicorganopolysiloxane block copolymers which are useful as protective coatings, surfactants and as elastomers.</p> |
