Butane‐1,2,3,4‐tetracarboxylic acid is reacted with hydrolyzed 3‐aminopropyltriethoxysilane (APTES) at 110 and 220°C (molar ratios 1 : 1 and 1 : 2). The as‐prepared materials were characterized by means of various analytical methods. FTIR measurements revealed the formation of a polyamic acid at 110°C whereas the treatment at 220°C resulted in the preparation of a polyimide. These findings were confirmed by means of SS‐ 13 C‐MAS‐NMR. XRPD experiments gave clear evidence for the formation of a specific periodic arrangement in the material. Thermogravimetric analysis indicated that the organic–inorganic material has improved thermal properties. All the materials obtained were insoluble in water and organic solvents. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
