| titleOfInvention | Method for producing ethylene copolymer |
| abstract | (57) [Summary] (with correction) [PROBLEMS] To have a narrow molecular weight distribution and a branching degree distribution and to control the composition distribution shape, and in particular, mechanical properties such as tear strength and impact strength, heat sealability, environmental stress crack resistance. To provide an ethylene copolymer which gives a film excellent in properties and the like, and a method for producing the same. SOLUTION: Mw / Mn measured by GPC method is 1. 5 to 4.0, Mw of 3,000 to 1,000,000, half-width at half maximum W / 2 of a curve obtained by Gaussian distribution approximation of the main peak of the composition distribution curve obtained by the temperature rising fractionation method, and average number of short chain branches n of the polymer Is expressed by the formula 0.704 + 0.147n ≦ W / 2 ≦ −0.055 + 0.577. An ethylene copolymer satisfying n and having a resin density of 0.85 to 0.95 g / cm 3 . A method for producing the same and an ethylene copolymer composition containing the copolymer. |
