titleOfInvention | Polymerization catalyst and method for producing the same |
abstract | The present invention relates to an N, N'-bis (trialkylsilyl) -2,2'-ethylenedianilinyl metal complex (N, N'-Bis ) And a production method thereof.n n n n n n n n n n Wherein R 1 is an alkyl group having 1 to 3 carbon atoms and M is a transition metal and Q is R 2 or R 4 wherein R 2 is chlorine, iodine, -N (CH 3 ) 2 or -N (C 2 H 5 ) 2 , and R 4 is an alkyl group having 1 to 7 carbon atoms. The compound of Formula 2 is very easy to synthesize and has a very high synthesis yield. Due to these advantages, it can be usefully used as a polymerization catalyst, and its activity is very high as compared with the conventional polymerization catalyst, so that a large amount of monomers can be polymerized even in a small amount. |
