Document Type and Number:
WIPO Patent Application WO/2018/143191
Kind Code:
A1
Abstract:
The present invention provides an ethylene polymer, wherein the viscosity-average molecular weight as determined according to specific conditions for measuring the isothermal crystallization time is 100 × 104 to 1,000 × 104 (inclusive), the ratio of the isothermal crystallization time at each of 125°C and 123°C is 3.5 to 10.0 (inclusive), and the degree of crystallization as determined from differential scanning calorimetry (DSC) is 40 to 75% (inclusive).
