Procedure
The materials flowed through the first three zones facilitated by stirring paddles along the reaction path. Polymerization continued to substantially 100% completion by the end of zone 4, thereby forming a “living” polyisoprene reaction mixture. At the start of zone 4, the solution of diphenylethylene in cyclohexane, solids of about 12 wt %, was added by a reciprocating piston pump (at a rate of 10.0 ml/min) to the “living” polyisoprene reaction mixture. This resulted in addition of a diphenylethylene-modified polyisopropenyl chain. This chain was treated at the start of zone 5 with a purified solution of 2-(N-methylperfluorobutanesulfonamido)ethyl methacrylate in toluene, solids of 20 wt % (fed by a reciprocating piston pump at rates of 2 and 10 ml/min) to form poly(isoprene-2-(N-methylperfluorobutanesulfonamido)ethyl methacrylate) block copolymers. The overall solids content of these reactions was about 32 wt %. The total residence time for these reactions was about 25 minutes.
