  • Copolymer, lubricating oil viscosity modifier, and lubricating oil composition
    Patent number: 7776805
    Abstract: A copolymer containing a constituent unit derived from ethylene and a constituent unit derived from an ?-olefin having 3 to 20 carbon atoms and satisfying the following requirements (1) to (5): (1) the copolymer has a melting point (Tm) of ?20° C. to 100° C.; (2) the melting point (Tm) and the density D (g/cm3) satisfy the following expression Tm?1073×D?893 (1); (3) the copolymer has a molecular weight distribution (Mw/Mn) measured by GPC of 1.6 to 5.0; (4) the copolymer has a half-width (?Thalf) of a melting peak measured by DSC of 90° C. or less; and (5) the half-width (?Thalf) and the melting point (Tm) satisfy the relationship shown by the following expression ?Thalf??0.71×Tm+101.4??(2).
