Jute slivers were acetylated in pilot scale following a no catalyst-no solvent method at 120ยฐC for 2 h. The weight % gain was found to be 11.37. Different jute boards were pressed under heat and pressure using acetylated jute sliver and urea formaldehyde resin. Neutral salt (NaCl), acid salt (NH 4 C

## Abstract Polyimide (PI)/silica hybrid membranes with high contact angles were prepared through the __in situ__ solโgel process. The precursor, poly(amic acid) with controlled block chain length, was synthesized using 4,4โฒโdiaminodiphenyl ether (ODA), 3,3โฒ,4,4โฒโbenzophenoneโtetracarboxylic dianhy
A series of chitosan membranes and their N-acetylated counterparts were prepared and their differences in acidic solution stability and thermal and mechanical properties were studied. The differences were attributed to differences in crystallinity of the membrane as the result of preparation conditi
