Summary
Methacryloyloxyl polytetrahydrofuran (MA-PTHF) macromer was prepared by the coupling method which involved the reaction of sodium methacrylate with living PTHF. The MA-PTHF macromer obtained by this method was shown to be highly pure macromer by a UV spectrometric method, indicating one vinyl group per molecule. The radical polymerization of the macromer was performed to check the polymerizability of the macromer. At a relatively high concentration of the macromer, it was homopolymerized at a high conversion of ca. 90%. Furthermore, the macromer was quantitatively copolymerized with styrene to the copolymer. This quantitative conversion is consistent with the high purity of MA-PTHF macromer obtained.
