The present invention provides ethylene polymers capable of preparing various molded articles such as films, sheets or the like, and having excellent moldability, particularly excellent high-speed moldability.The ethylene polymers of the present invention have a density and molecular weight distribution in specific ranges.The first ethylene polymer is characterized by having (C) a ratio (MFR.sub.10/MFR.sub.2) of a melt flow rate (MFR.sub.10) at 190.degree. C. under a load of 10 Kg to a melt flow rate (MFR.sub.2) at 190.degree. C. under a load of 2.16 Kg of from 16.2 to 50. The second ethylene polymer is characterized by having (C) a ratio (MFR.sub.10/MFR.sub.2) from 12 to 50. The third ethylene polymer is characterized by having (D) a relation of .omega.2/.omega.1.gtoreq.18 where .omega.1 and .omega.2 denote angular velocity (rad/sec) when complex elastic modulus G* (dyne/cm.sup.2) at 200.degree. C. is 5.0.times.10.sup.5 dyne/cm.sup.2 and 2.0.times.10.sup.6 dyne/cm.sup.2, respectively, which are determined by measurement of the angular velocity dependence of the complex elastic modulus of the copolymer.
