摘要：
An ethylene/α-olefin copolymer, which:
(1) comprises 30 to 80% by mol ethylene and 20 to 70% by mol C3 to 10 α-olefin;
(2) has a number-average molecular weight (Mn), as determined by gel permeation chromatography (GPC) of 500 to 12,000 and a molecular weight distribution (Mw/Mn) of 3 or less;
(3) has a kinetic viscosity at 100°C of from 10 to 5,000 mm 2 /s;
(4) has at least one unsaturated bond at a molecular terminal of at least 95% of the polymer chains; and
(5) has a B value, as determined by formula (I), of from 1.0 to 2.0: B = P OE / 2 P O . P E
wherein P E is the molar fraction of the ethylene unit in the copolymer, P O is the molar fraction of the α-olefin unit in the copolymer, and P OE is the proportion of the number of α-olefin/ethylene sequences to the number of all the dyad sequences in the copolymer.
