Web1 jul. 2005 · In our study, we obtained 3α,12α-dimethacryloyl cholic acid methyl ester (5) when methacryloyl chloride was used as the acylating agent. Compounds 5 and 9 were first obtained (before compounds 6 and 10). The NMR spectra in Fig. 2 clearly show that C12-OH has a higher reactivity for methacryloyl chloride than C7-OH. WebThe vinyl ester acted as terminator ( terminator method ). In using vinyl methacrylate (12.5 mol % or 15 mol % based on DDL) and lipase PF as terminator and catalyst, respectively, the quantitative introduction of methacryloyl group at the polymer terminal was achieved to give the methacryl-type macromonomer (Fig. 12).
