Synthesis of poly(n-butyl acrylate)

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 (S,S-dibenzyl trithiocarbonate) (0.158 g, 0.544 mmol),
n-butyl acrylate (8.00 g, 62 mmol),
PGMEA (5.1 g), and
[1] (3.13 g, 0.136 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 2 hours in an oil bath at 75ºC under nitrogen atmosphere.
5
Poly(n-butyl acrylate) with Mw = 13,900, Mw/Mn = 1.20 is obtained by GPC analysis of the formed polymer.
