Theoretical model of interfacial polymerization

The Journal of Chemical Physics, 2004
We present a theoretical description for the creation of a thin polymeric layer through the interfacial polymerization of two immiscible, low molecular weight liquids. The theory specifically takes into account the effects of polydispersity on the formation of the polymer film at the liquid-liquid interface.

Synthesis of Uniform Polyaniline Nanofibers through Interfacial Polymerization [PDF]

Materials, 2012
The present paper aims to study the preparation of polyaniline nanofibers through simple interfacial polymerization. Ammonium persulfate, hydrochloric acid and chloroform were used as oxidant, dopant and organic solvent respectively.

Interfacial polymerization of aniline

Journal of the Chemical Society, Chemical Communications, 1994
Chemical oxidation of aniline at the liquid/liquid interface of two immiscible solvents results in the growth of an electroactive polymer membrane that exhibits redox behaviour similar to conventional electrodeposited polyaniline.

Interfacial polymerization of an isocyanate and a diol

Journal of Polymer Science: Polymer Chemistry Edition, 1985
AbstractThe interfacial reaction between a liquid polyfunctional aromatic isocyanate and a diol was studied using infrared spectroscopy to follow the reduction in concentration of the isocyanate group. It was shown that the product polyurethane formed a gel layer around dispersed isocyanate droplets which were swollen by the diol but not by the ...

Interfacial and Dispersion Polymerization

1989
The method of interfacial polycondensation was first applied by Einhorn1 in 1898 to obtain a polycarbonate by means of the interaction of phosgene dissolved in toluene with a hydroquinone water–alkali solution. Subsequently, however, this work was forgotten, and only in the 1950s did it become clear that interfacial polycondensation opens up extensive ...

Mechanism of interfacial polymerization

Transactions of the Faraday Society, 1969
A study has been made to try to elucidate the locus of polymerization and mechanism of an interfacial polycondensation between sebacoyl chloride and hexamethylenediamine. It is concluded that polymerization occurs in a mixed monolayer of the adsorbed monomers.

Interfacial oxidative polymerization of phenothiazine

Polymer Science Series B, 2009
Phenothiazine polymers have been prepared for the first time by interfacial oxidative polymerization. Effects of the concentration and ratio of reagents, temperature, and time of reaction on the yield and molecular mass characteristics of polyphenothiazine are investigated.

Thick Silicate Film by an Interfacial Polymerization

Journal of Sol-Gel Science and Technology, 1997
A thick silica gel film, corresponding to the glass film of 10–20 micron in thickness, has been formed at the interface between two immiscible liquids, hexane and water, using E-40, a partially polymerized silicon alkoxide, as the precursor. The film formation was possible using both acid- and base-catalyzed water, but was greatly dependent on the type
