An example of polymerization

Synthesis of polymethyl methacrylate

  • 1

    Add V-601 (100 mg) and PGMEA (9.90 g) to a 10-mL vial to prepare 1 wt% PGMEA solution.

  • 2

    To a 50-mL eggplant-shaped flask,
    Add RAFT agent (4-cyano-4-[(dodecylsulfanylthiocalbonyl)sulfanyl] pentanoic acid) (0.346 g, 0.856 mmol),
    Methyl methacrylate (12.5 g, 125 mmol),
    PGMEA (8.0 g)
    [1] (4.89 g, 0.213 mmol as V-601), and allow them to dissolve.

  • 3

    When [2] is completely dissolved, attach a reflux tube and conduct bubbling with nitrogen for 30 minutes under room temperature.

  • 4

    Let it react for 5 hours in an oil bath at 75ºC under nitrogen atmosphere.

  • 5

    Polymethyl methacrylate with Mw = 12,100, Mw/Mn = 1.14 is obtained by GPC analysis of the formed polymer.
