Silica-type materials with different structure and morphology, synthesized using sol-gel process, were applied as a carriers of organometallic catalytic systems (VOCl3/AlEt2Cl) for ethylene-1-hexene copolymerization. Carrier materials, prior to immobilization of the vanadium compound, were pre-treated using two modes: one-step thermal modification and two-steps modification including additional reaction...
Sol-gel technique was employed to obtain the silica-type powder, which after modification procedure was applied as a support of organometallic catalytic system for ethylene polymerization. The powder product was synthesized using hydrolysis and condensation of TEOS, catalyzed by ammonia. Obtained material and a reference support (commercial' silica Davisil) were characterized to determine their particle...
