Most of the previously reported dinuclear catalysts contain two mononuclear complexes connected by a fl exible tether. Herein we report double - decker type dinuclear complex catalysts having two metal centers located on cyclic ligands in close proximity. They show a higher catalytic activity than the mononuclear analogue, and gave polymers with higher molecular weight. The dinuclear catalysts also promote copolymerization of ole fi ns with various comonomers and gave copolymers with unique structures. It was also revealed that the dinuclear catalysts are stable at elevated temperature.","PeriodicalId":17878,"journal":{"name":"Kobunshi Ronbunshu","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80184430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The addition of phenols with electron withdrawing groups increased the turnover frequency ( TOF ) of the catalyst, while the addition of non - substituted phenol and monosilanol had a negative effect on the TOF. These results indicate that the Lewis acidity of aluminoxane was enhanced by the modi fi cation with electron de fi cient phenoxides. The decrease of the stereoregularity of the obtained polypropylene accompanied by the increase of TOF supported this interpretation. These fi ndings could be extended to explain the cocatalytic behavior of MMAO supported onto silica.","PeriodicalId":17878,"journal":{"name":"Kobunshi Ronbunshu","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82314604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
