Abstract:
1. A preparation method of a hybrid supported metallocene catalyst, comprising the steps of: treating a support having a water content of 4 to 7% by weight with trialkyl aluminum at a temperature of 60 to 100° C.; supporting an alkyl aluminoxane on the support; and supporting a metallocene compound on the alkyl aluminoxane-supported support, wherein the metallocene compound is one or more selected from the group consisting of the following Chemical Formulae 1 to 3: wherein M is a Group 4 transition metal; (C Q is a halogen atom, alkyl, alkenyl, aryl, alkylaryl, arylalkyl or alkylidene; p is 0 or 1; wherein M is a Group 4 transition metal; R A is alkylene having 2 to 4 carbon atoms, alkylsilicon having 1 to 4 carbon atoms, alkylgermanium having 1 to 4 carbon atoms, alkylphosphine having 1 to 4 carbon atoms or alkylamine having 1 to 4 carbon atoms; Q is each independently a halogen atom, alkyl having 1 to 20 carbon atoms, alkenyl having 2 to 10 carbon atoms, alkylaryl having 7 to 40 carbon atoms, arylalkyl having 7 to 40 carbon atoms, aryl having 6 to 20 carbon atoms, substituted or unsubstituted alkylidene having 1 to 20 carbon atoms, substituted or unsubstituted amino group, alkylalkoxy having 2 to 20 carbon atoms or arylalkoxy having 7 to 40 carbon atoms; m is an integer of 0 to 10; wherein R R CY M is a Group 4 transition metal; and Q
