Abstract
Provided is a polymer composition having a melt index of 0.01 to 5.0 and a density of 0.880 to 0.940 prepared by blending 10 to 80 parts by weight of an ethylene/.alpha.-olefin copolymer having an intrinsic viscosity determined in decalin at 135.degree. C. of 2.0 to 10 dl/g and a density of less than 0.91 which copolymer is obtained by copolymerizing ethylene with an .alpha.-olefin of C.sub.3 to C.sub.12 in vapor phase condition, with 20 to 90 parts by weight of an ethylene polymer having an intrinsic viscosity determined in decalin at 135.degree. C. of not higher than 1.7 dl/g and a density not less than 0.950.
