摘要： A polyethylene powder satisfying (Requirements 1 to 3) :
(Requirement 1): viscosity-average molecular weight (Mv) is 200,000 or more and 3,000,000 or less
(Requirement 2): complex viscosity |η*| m obtained by measurement under predetermined satisfies the following formula (1): 590.0 × Mv × 10 − 4 1.18 ≥ η * m ≥ 13.3 × Mv × 10 − 4 1.18
(Requirement 3): a value of any peak when d(log|η*|)/dT is plotted against temperature is 1.0 or more and 3.0 or less.
