Methyl Acrylate → HCID 22731677, compound

Participants

Reaction Steps

A degassed solution of the oligomer prepared in Example 26 (100 mg) in styrene (3 ml) was heated at 100° C. for 3 hr. At the start of the reaction and after each hour of heating di-t-butylnitroxide (0.5 mg) was added in order to suppress the thermal initiation of styrene. Removal of volatiles gave the title AB block co-oligomer. HPLC fractionation, together with 1H NMR analysis, proved that the styrene units were attached to the starting methyl acrylate oligomer. 1H NMR (90 MHz) δ: 0.7-1.3 (C--CH3), 1.3-2.6 (CH2 --CH), 3.3-3.55 (COOCH3 next to Ar), 3.65 (COOCH3), 6.3-7.4 (ArH).
