높은 내응력균열성을 갖는 폴리에틸렌 조성물
摘要：
하기특징들을갖는압출코팅에특히적합한저밀도폴리에틸렌이제공된다: 1) 23℃에서 ISO 1183에따라측정한, 0.930 내지 0.945 g/cm의밀도; 2) 30 내지 55 미만의 MIF/MIP 비; 3) 3 내지 25 g/10분 g/10분의 MIF; 4) 1,500,000 g/mol 이상의 Mz; 5) 0.55 이하의장쇄분지지수, LCBI; 여기에서, LCBI는 GPC-MALLS로측정한, 측정평균제곱회전반경 R대동일한분자량을갖는선형 PE에대한평균제곱회전반경의비이다.
摘要（英）：

Is particularly suitable low-density polyethylene for extrusion coating having the following features is provided:
1) a density of 0.930 to 0.945 g / cm 3 measured in accordance with ISO 1183 eseo 23 ℃;
2) less than 30 to 55 MIF / MIP ratio;
3) 3 to 25 g / 10 min g / 10 min MIF;
4) more than 1,500,000 g / mol Mz;
5) long chain branching index of 0.55 or less, LCBI;
Here, LCBI is the ratio of mean square radius of rotation for linear PE having a, measuring the mean square radius of rotation R g for the same molecular weight as measured by GPC-MALLS.
