| 摘 要： | 研究了乙烯/辛烯-1共聚合制备线性低密度聚乙烯(LLDPE)。发现共聚活性高于乙烯均聚。用~(13)C-NMR 测定了共聚物的组成及序列分布。讨论了共聚物支化度和共聚物性质的关系。

Preparation of LLDPE with High Efficiency Supported Ti Catalyst Ⅰ.Ethylene/Octene Copolymerization |
| |
| Abstract: | Ethylene/1-octene copolymerization over a titanium/magnesium catalyst wasstudied.It was found that the catalytic efficiency increased significantly when thecomonomer was present in the polymerization.The coordination effect of the co-monomer with the active centers was identified.Copolymer composition and mono-mer distribution were determined by ~(13)C-NMR and IR methods.The relationshipbetween the comonomer incorporation and some physical properties of the co-polymers were also investigated. |
