In recent years, the research and development of new polyolefin catalysts continue to make a breakthrough , following the metallocene catalyst after the revolutionary change is caused by non-metallocene catalyst increasingly attracted people's attention . To salicylaldehyde with aniline , o-phenylenediamine as raw materials, synthetic N- salicylaldehyde aniline , N , N' - salicylaldehyde o- phenylenediamine , the use of these two ligands with titanium tetrachloride , ferric chloride, tetrabutyl titanate complex , synthesized eight new Schiff base metal complexes . Synthesized Schiff base metal complexes with a cocatalyst Grignard reagent composition of the catalytic system , the system of the Reaction of this new catalytic system for the catalytic polymerization of styrene . The effects of the polymerization reaction temperature , the catalyst system composition , the amount of catalyst, monomer concentration , Mg / Ti molar ratio , the polymerization time , the kind of solvent and the amount of the influence factors on the polymerization of styrene . < / Sup > C - NMR , IR , DSC and X- ray diffraction test use 13 means on the part of the polymer were characterized . The results show that the polymerization system found the mechanism of coordination polymerization , the polymer structure having a certain orderly .
