Abstract:
1. A method of preparing a cyclic olefin polymer by addition polymerization of a cyclic olefin monomer, the method comprising contacting a metal catalyst complex represented by Formula 1 below with a cyclic olefin monomer represented by Formula 2 below: wherein M is a Group X metal, [M(L L L′ L [Ani] is an anion capable of weakly coordinating with the metal M, x is 1 or 2; y is 0 to 4; z is 1 or 2; 2≦x+y+z≦6, a and b are respectively the number of cations and the number of anions capable of weakly coordinating with the metal M and are each a number of 1-10 which is used to satisfy the net charge balance of the metal catalyst complex, wherein for each of L wherein m is an integer of 0 to 4, R R wherein the nonpolar functional group is selected from the group consisting of hydrogen; halogen; C1C20 straight or branched alkyl, haloalkyl, alkenyl, or haloalkenyl; C3-C20 straight or branched alkynyl or haloalkynyl; C3C12 cycloalkyl which is unsubstituted or substituted by alkyl, alkenyl, alkynyl, halogen, haloalkyl, haloalkenyl, or haloalkynyl; C6C40 aryl which is unsubstituted or substituted by alkyl, alkenyl, alkynyl, halogen, haloalkyl, haloalkenyl, or haloalkynyl; and C7C15 aralkyl which is unsubstituted or substituted by alkyl, alkenyl, alkynyl, halogen, haloalkyl, haloalkenyl, or haloalkynyl, and wherein the polar functional group is a non-hydrocarbonaceous polar group comprising at least one of oxygen, nitrogen, phosphorus, sulfur, silicon, and boron, and is selected from the group consisting of: —R where R R k's are each an integer of 1 to 10.
