ABSTRACT:
A poly(organosiloxy) telechelic styrene polymer polymerization process comprising contacting an olefin, a free radical polymerization initiator, and a poly(organosiloxyaryl) polysulfide is described. The poly(organosiloxy) terminated styrene polymers can be end capped and/or coupled with other polymeric materials. The styrene polymers can be molded, calendered, or extruded as films, sheets, fibers, laminates or other useful articles of manufacture.
