14. 1H NMR spectral data were 3.25 and 1.71 mmol equiv./g, respectively.
15. 4-) were used.

17. A mixture of 2 (0.11 g, 0.25 mmol equiv. of diethyldithiocarbamate unit) and 3 (0.11 g, 1.12 mmol) in THF (2 mL) was fed into a glass tube and sealed after three freeze-pump-draw cycles. Then, the mixture in the glass tube was irradiated at room temperature by using a RIKO RH400 UV lamp equipped with water jacket from a distance of 10 cm.
18. -1 under nitrogen.
19. The solution of 2 or 4 in toluene was cast on polyethylene sheet and, then, removed toluene at 120°C for 1 min in an oven. Static contact angles on 2 and 4 were measured with deionized water drops on the resulting sheet at room temperature.
20. n of 4, isolated as an insoluble part of diethyl ether, were 3100 and 1.58, respectively. The contents of the functional groups were estimated as follows: phenyl group = 1.95 mmol equiv./g, diethylamino group = 1.05 mmol equiv./g, and dimethylacrylamide unit = 4.55 mmol equiv./g.
21. n of the poly(N,N-dimethylacrylamide) used as the sample compared with 4 were 13000 and 1.20, respectively.
