Abstract

HROMNI KATALITIČKI SASTAVI I POSTUPAK ZA POLIMERIZACIJU ISTIM, pronalazak se odnosi na hromni katalitički sastav. Ovi hromni katalitički sastavi mogu da se koriste da se polimerizuju olefini, pri čemu dobijeni polimerizacioni proizvod može da ima poboljšana svojstva. Hromni katalitički sastavi prema pronalasu sadrže najmanje dva hromna katalitička sistema koji sadrže hrom i nosač, gde nosač sadrži silicijum dioksid. Hromni nosači različitih sistema imaju razliku prosečnog prečnika pore dovoljnu da se prvenstveno uvodi neetilenski komonomer u deo više molekulske mase nastalog polimera. Pronalazak se odnosi i na postupak za polimerizaciju u kojoj se koriste hromni katalitički sastavi prema pronalasku.
