| titleOfInvention | Catalyst for polymerization of syndiotactic styrene polymer and method for preparing syndiotactic styrene polymer using the same |
| abstract | The present invention relates to a polymerization catalyst for producing a vinyl aromatic polymer and a method for producing a polymer using the same, and in particular, a trifluoromethyl sulfonyl group 4 transition metal catalyst for producing a syndiotactic styrene polymer and a syndiotach using the same. It relates to a method for producing a tic styrene polymer.n n n The present invention provides a catalyst for syndiotactic styrene polymerization represented by the following formula (1).n n n [Formula 1]n n n R ℓ M [X (SO 2 CF 3 ) k ] m Y n n n n Wheren n n M is titanium, zirconium, or hafnium, R is cyclopentadienyl, indenyl, fluorenyl, or a derivative thereof, Y is an alkyl group, aryl group, allyl group, alkoxy group, aryloxy group, thioalkoxy group, Thioaryloxy group, amino group, amide group, carboxyl group, alkyl cyryl group, or halogen, X is methine (-CHR'-, wherein R 'is hydrogen, alkyl group having 1 to 20 carbon atoms, allyl group, aryl group, Or a cycloalkyl group), alkyl silicon, alkyl germanium, alkyl boron, alkyl aluminum, N, NR '(where R' is hydrogen, an alkyl group having 1 to 20 carbon atoms, an allyl group, an aryl group, or a cycloalkyl group), P, PR ″ (where R ″ is an alkyl group, allyl group, aryl group, or cycloalkyl group having 1 to 20 carbon atoms), oxygen, or sulfur and l and m are each an integer of 1 or more, n is an integer of 0 or more, and + m + n = 4 and k is an integer of 1-3. The present invention also provides a method for producing a syndiotactic styrene polymer using the catalyst.n n n In the catalyst of the present invention, when the element connected to the central metal in the transition metal compound is nitrogen or carbon, it is possible to construct a highly active catalyst system only with a promoter which is alkyl aluminum, alkyl aluminoxane, or a mixture thereof. |
