A novel metastable layered titanium phosphate has been synthesized by the treatment of layered titanates (Na2Ti3O7 and Na4Ti9O20) with 1–2 M phosphoric acid solution at 120–150 °C. Based on the data of 31P MAS NMR and IR spectroscopy, x-ray powder diffraction, and thermal and elemental analysis, the formula Ti2O3(H2PO4)2 · 2H2O was assigned to the novel compound. The layered nature of the compound was confirmed from n-alkylamine intercalation and the ion exchange behavior toward alkali, alkaline earth, and some transition metal ions.

Solution Polycondensation

The solution polycondensation of 1-(4-aminophenyl)-5(6)-aminoindane (DAPI) with a number of commercially available dianhydrides using the two-step ester-acid solution imidization route is described. High molecular weight polyimides were successfully synthesized from a 1:1 molar ratio of dianhydride to diamine. These film-forming systems have high glass transition temperatures (331–368 °C) and very good short-term thermal stability as judged by differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA). The fully cyclized polyimides are also highly soluble in common solvents.
