Polymeric pseudo-liquid membranes from poly(dodecyl methacrylate) : KCl transport and optical resolution

Polymeric pseudo-liquid membrane (PPLM) was constructed from poly(dodecyl methacrylate), which showed rubbery state under membrane transport conditions, as a membrane matrix and dibenzo-18-crown-6 or O-allyl-N-(9-anthracenylmethyl)cinchonidinium bromide as a model transporter. Membrane performance was studied adopting KCl or racemic mixture of phenylglycine as a model substrate. The present results suggest that PPLMs were applicable to not only metal ion transport but also optical resolution.
