    摘要: Provided is a process which can be carried out upon the production of a polyurethane/thiourethane-based resin with the use of a polyisocyanate compound, a polyol compound, and a polythiol compound, without causing abrupt heat generation or viscosity increase. At least one polyol compound having at least one ether bond and two or more hydroxy groups in a molecule is used as the polyol compound, whereby a large heat generation or an abrupt viscosity increase are prevented from occurring upon blending monomer.

    摘要: Copolymers when used as lubricating oil viscosity modifiers enable lubricating oils to show excellent low-temperature properties. Processes for producing the copolymers are disclosed. Lubricating oil viscosity modifiers and lubricating oil compositions contain the copolymers.A copolymer includes structural units derived from ethylene and structural units derived from a C3-20 α-olefin and satisfies the following requirements (1) to (8): (1) the melting point (Tm) according to DSC is in the range of 0 to 60° C.; (2) the melting point (Tm) and the density D (g/cm3) satisfy the equation: Tm≧1073×D−893; (3) Mw/Mn according to GPC is from 1.6 to 5.0; (4) the half-value width (ΔThalf) of a melting peak measured by DSC is not more than 90° C.; (5) the half-value width (ΔThalf) and the melting point (Tm) satisfy the equation: ΔThalf≦−0.71×Tm+101.4; (6) the heat of fusion (ΔH) as measured by DSC is not more than 60 J/g; (7) the crystallization temperature (Tc) measured by DSC is not more than 70° C.; (8) the heat of fusion (ΔH), the crystallization temperature (Tc), each measured by DSC and the crystallization temperature measured by a CRYSTAF method (Tcrystaf) satisfy the equation: Tc−Tcrystaf≧0.028×ΔH+25.3.
