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.
