Abstract
Anionic copolymerizations of 1,1-diphenylethylene (DPE) with o- and p-methoxystyrene (o- and p-MeOSt) were investigated with n-butyllithium (n-BuLi) and other anionic initiators. In THF, alternating copolymers of DPE with o- and p-MeOSt were obtained. In aromatic hydrocarbons, the copolymerization of DPE and o-MeOSt with n-BuLi gave a polymer having higher o-MeOSt content, while an almost alternating copolymer was obtained in the copolymerization of DPE and p-MeOSt. The NMR spectra of the alternating copolymers of DPE with o- and p-MeOSt showed the splittings due to the tactic difference with respect to the methoxy group. The latter alternating copolymer was shown by polarized light and X-ray examinations to be crystalline.
