Abstract
A method of making an ethylene-propylene (EP) copolymer includes immobilizing a metallocene catalyst on a layered double hydroxide (LDH) to form a supported metallocene catalyst complex. The method also includes mixing the supported metallocene catalyst complex in a nonpolar solvent to form a first mixture. The method further includes degassing the first mixture and saturating with a gaseous mixture of ethylene and propylene to form a second mixture. The method further includes mixing an aluminoxane catalyst with the second mixture to initiate a polymerization reaction of the ethylene and propylene to form a reaction mixture comprising the EP copolymer and separating the EP copolymer from the reaction mixture.
