Reaction Conditions

Reaction Steps

A mixture of the polymeric macroinitiator, 6 (2.0 g, 0.30 mmol, Mw) 7200, PDI) 1.09), styrene (0.258 g, 2.48 mmol), and 5 (0.916 g, 4.15 mmol) was dissolved in chlorobenzene (2.9 mL), degassed by four freeze/pump/thaw cycles, and sealed under argon. The polymerization mixture was then stirred at 124° C. for 16 h and allowed to cool, and the star polymer, 16, was obtained after precipitation into methanol (3.1 g, 90%, Mw) 49400, PDI) 1.58). 1H NMR (CDCl3): δ (ppm) 6.32-7.2 (br m), 0.81-2.12 (br m).
