<p>The present invention relates to a method for producing an ethylene polymer, comprising:
a step of polymerizing olefins including ethylene, in the presence of an olefin polymerization catalyst comprising:
[A] a solid titanium catalyst component including magnesium, halogen, titanium and a polyether compound represented by the following general formula (2), and

[B] an organometallic compound catalyst component including a metal element selected from group I, group II and group XIII of the periodic table; and
(c) a step of subjecting the polymer obtained in the above step to a temperature of not less than 100°C and not more than a melting point of the polymer for 15 minutes to 24 hours;
wherein m is an integer of 1≤m≤10; R<Sup>11</Sup> to R<Sup>36</Sup> represent each independently a hydrogen atom or a substituent having at least one element selected from carbon, hydrogen, oxygen, fluorine, chlorine, bromine, iodine, nitrogen, sulfur, phosphorus, boron and silicon; when m represents 2 or more, a plurality of R<Sup>11</Sup>s and R<Sup>12</Sup>s may each be the same or different; and any of R<Sup>11</Sup> to R<Sup>36</Sup> may together form a ring other than a benzene ring.</p> |
