-
Paragraph 0117, (2020/11/06)
PROBLEM TO BE SOLVED: To provide a viscosity index improver excellent in shear stability, and a lubricant composition containing the viscosity index improver. SOLUTION: The invention provides a compound represented by the general formula (1) in the figure, and a polymer comprising a constitutional unit (a) derived from the general formula (1). (In the general formula (1), R1 represents a hydrogen atom or methyl group; R2, R3, R4 and R5 each independently represent a C2-18 alkyl group; and m and n each independently represent an integer from 1 to 10.)

Page/Page column 5, (2012/01/14)
The present invention relates to a process for producing an ether compound in a simplified, efficient manner, including the step of reacting a hydroxyl group-containing compound with an epoxy compound in the presence of an oxide of a metal of Group 4 of the Periodic Table on which a sulfate ion is supported, wherein a sum of a diffraction intensity of a (111) crystal lattice plane and a diffraction intensity of a (?111) crystal lattice place of the metal oxide is 2000 cps or larger as measured by subjecting the metal oxide to powder X-ray diffraction analysis.

Page/Page column 9, (2010/03/31)
New polyol ether compounds and a process for their preparation. The process comprises reacting a polyol, a carbonyl compound, and hydrogen in the presence of hydrogenation catalyst, to provide the polyol ether. The molar ratio of polyol to carbonyl compound in the process is greater than 5:1.
