Novel Multinuclear Half Metallocene Catalysts and Method for Preparing of Syndiotactic Polystyrenes Using The Same

摘要

The present invention and a syndiotactic styrene polymer having the use of a small amount of cocatalyst, and high activity, superior stereoregularity, high melting temperature and various molecular weight distributions for the preparation of the active, from the periodic table Group III Group 10 the combination of the cycloalkane cyclopentadienyl group or a derivative thereof to produce a five-coordinate bonding to one side of the transition metal and the other is having a metallocene structure of a plurality of combined phenolic amine or phenolic compound is introduced in multi-nuclear half metal having a seat multiple nuclear transfer of a novel structure relates to a process for preparing a metallocene catalyst and a styrene-based polymer using the same metal as the metal halves. ; Metal half metallocene catalyst, a multi-nuclear phenolic amine, a phenol, a syndiotactic polystyrene, alkyl aluminum dioxane
