Alternating Copolymers

<p>Poly(ferrocenylsilane)s containing Si-vinylene unit in the main chain have been synthesized by Mizoroki-Heck reaction of 1,1’-bis(dimethylvinylsilyl)ferrocene (MVFS) and dibromo aryl compounds using palladium diacetate as a catalyst. The alternating copolymers with relatively low molecular weight were obtained in good yields. Cyclic voltammetry of the copolymers in CH<sub>2</sub>Cl<sub>2</sub> solutions showed redox potential derived from the ferrocene units in the copolymers. The voltammograms the copolymers indicated that almost no difference in numbers of electron transfer compared with MVFS. By contrast, diffusion coefficients of the ferrocene units in the copolymers were smaller than that of MVSF. The copolymers showed reversible electrochromism from yellow to blue-green due to the redox of ferrocene units in the main chain by 3V of application.</p>

Phase Inversion Method

Polyetherimide (PEI) with excellent solvent resistance and thermal resistance is a good membrane material which is studied in detail. PEI ultrafiltration membrane with low molecular weight cut-off is prepared by phase inversion method in this work. The membrane showed high resistance to PEG1000 which can be used in wastewater treatment with organic solvent.
