Knowledge of rheological properties of polymer and their variation with temperature and concentration have been globally important for processing and fabrication of polymers in order to make useful products. Basheer et al. [1] investigated, experimentally... see more

Porous organic polymers (POPs) have received much attention in adsorption, separation, and catalysis. In this paper, porous organic polymers with different pore structure were used as metallocene catalyst supports, and ethylene/1-hexene copolymerizations ... see more


Ethylene/1-hexene copolymerization was performed over titania-supported zirconocene/dMMAO catalysts. Effects of titania having different phases on the catalytic activity and polymer properties were investigated. It was found that anatase titania exhibited... see more

Nano-TiO2 and its modification with gallium (nano-TiO2-Ga) and zirconium (nano-TiO2-Zr) were used here as nanofillers in production of linear low-density polyethylene (LLDPE). The nanoparticles were immobilized by modified-methyl aluminoxane (MMAO) to be ... see more

The two different kinds of impregnation (in situ and ex situ were used in the heterogeneous copolymerization of ethylene and 1-hexene for production of LLDPE/silica composite. For the ex situ impregnation, MMAO cocatalyst was immobilized firmly onto the s... see more
