    • 2. To 1, swollen in THF (4 mL), EPK (105 mg, 0.718 mmol) was added at -20 °C and shaken at the same temperature for 10 min. After the mixture cooled to -78 °C, a suspension of LiCl (64 mg, 1.5 mmol) in THF (2 mL) and MMA (299 mg, 2.99 mmol) was successively added. After the mixture was shaken for 3 h at -78 °C methanol (0.5 mL) was added to quench the reaction. The mixture was filtered, and the residual resin was washed successively with THF, water, and methanol and was dried in vacuo to obtain the resin 5 (517 mg). 5 was swollen in TFA (50% in DCM, 6 mL) and shaken at room temperature for 3 h. The mixture was filtered, and the residual resin was washed with DCM. The filtrate was concentrated unde reduced pressure and dried in vacuo to give a mixture (279 mg) of PMMA with an oligoester at the terminal 6 and the oligo-EPK 4.
