N2 - The aim of this work was to study the effect that various copolymers and several synthesis conditions may have on the properties of mesoporous aluminophosphates obtained using AlCl3 and H3PO 4 as aluminium and phosphorous precursors, respectively under non-aqueous conditions. Poly(styrene-co-allyl alcohol) and various triblock type copolymers were used as structure-directing agents in an acidic medium. The parameters investigated using the poly(styrene-co-allyl alcohol) included stirring time, Al/P mole ratio, synthesis time at 40 C, calcination temperature and the type and amount of polymer used. The resulting materials were characterized by nitrogen adsorption at -196 C, X-ray diffraction (XRD), temperature-programmed ammonia desorption (TPD-NH3) and transmission electron microscopy (TEM). Mesoporous aluminophosphates with surface areas up to 540 m2/g were obtained.
