Abstract:
An ethylenic copolymer comprising ethylene and an &agr;-olefin in which diad chain distribution [EA] of ethylene [E] and &agr;-olefin [A] as determined by the nuclear magnetic resonance spectrum method (13C-NMR method) and ethylene content (e) (mol %) as determined by nuclear magnetic resonance spectrum satisfy:0.7âˆ’2.8(0.5âˆ’(e)/100)2âˆ’|0.25(0.5âˆ’(e)/100)|&lE;[EA]&lE;2(e)/100â€ƒâ€ƒ(1) 23e)&lE;49â€ƒâ€ƒ(2) in which said &agr;-olefin has 3 to 20 carbon atoms, and wherein the copolymer has a kinematic viscosity at 100Â° C. of 2 384.5 to 797.7 (mm2/sec) and a pour point of âˆ’20 to âˆ’25Â° C.
