Novel polydiorganosiloxylated thiuram disulfides and radical polymerization of vinyl monomers therewith

摘要

Novel polydiorganosiloxane substituted thiuram disulfides have the formula: ##STR1## and are useful for the radical polymerization of vinyl monomers to produce polydiorganosiloxane/polyvinyl/polydiorganosiloxane block copolymers having improved physical properties.
