Abstract: An ethylene polymer which contains 0.02-1.50 mol% structural units derived from a C6-10 α-olefin and has a density of 945 to 975 kg/m3 and which satisfies both of the following requirements [1] and [2]. The ethylene polymer is excellent in flowability and moldability and gives a molding having excellent mechanical strength. [1] In CFC, all the components having a molecular weight of 100,000 or higher are eluted at temperatures not lower than 85°C. [2] The components eluted at temperatures not higher than 80°C account for up to 5% of all the components eluted in CFC.

Abstract: Ethylene (co)polymers excellent in moldability, mechanical characteristics and so on and suitable for various moldings, particularly pipes. For example, ethylene homopolymers or ethylene/C4-C20 α-olefin copolymers, wherein the number of methyl branches is less than 0.1 per 1000 carbon atoms as determined by 13C-NMR and the Mw/Mn ratio is 1.8 or above but below 4.5 as determined by GPC; and ethylene homopolymers or ethylene/C¿3?-C20 α-olefin copolymers, wherein the melt tension (MT) and the swelling ratio (SR) satisfy the relationship: log(MT) > 12.9 - 7.15 x SR, and the intrinsic viscosity ([θ]) and the melt flow rate (MFR) satisfy the relationship: [θ] > 1.85 x MFR?-0.192¿ in the case of MFR 1.85 x MFR-0.213 in the case of MFR ≥ 1.

Abstract: A thermoplastic resin composition which comprises: (A) 100 parts by weight of a thermoplastic resin, (B) 0.01 to 30 parts by weight of a surfactant, and (C) 0.01 to 30 parts by weight of a functional organic compound having 0.1 to 10 mmol/g functional groups in which two atoms (a and b), bonded to each other have net charges (Ea and Eb), respectively, as calculated by the molecular orbital method. The net charges satisfy the following relationship (1): 0.25≤IEa-EbI≤0.7. When this composition is formed into a film, etc., the product stably retains antistatic performance and antifogging performance from immediately thereafter over long.
