Titanium oxide ST01, ST31, TiO2 catalysts modified by V5+, N2+ and supported on MCM41 and SiO2 have been used for photooxidation of p-xylene in gas phase. Physicochemical properties of catalysts were determined by the methods of BET Adsorption, Xray Diffraction (XRD), UV-Vis spectroscopy, and atom adsorption spectroscopy (AAS) methods. The photocatalytic activity of catalysts were determined after thermal treatment as well as UV lighting. The common observation is that the higher temperature of treatment the lower conversion of p-xylene obtained.

The presence of dicumyl peroxide (DCP) causes the changes in relative melt viscovity and the morphology of blend LLDPE/EVA. It raises torque momen amplitude of polymer blend at the balance state of melting of the polymers mixture. The results of TGA show that the durability against thermo-oxidation of polymer blend containing DCP is higher than that of without DCP. The SEM photographs also shows that DCP makes LLDPE and EVA phases dispersing into each other better than the original polymer blend.
