Title:
LUBRICANT COMPOSITION AND METHOD FOR PRODUCING COPOLYMER UTILIZING THE SAME
Document Type and Number:
Japanese Patent JP2021014576
Kind Code:
A
Abstract:
To provide a lubricant composition capable of suppressing formation of a self-polymerization product in a polymerization step by interaction with a polymerization inhibitor and a polymerization inhibition accelerator.SOLUTION: The lubricant composition of an embodiment of the present invention comprises: a base oil; a phenothiazine-based polymerization inhibitor; and the polymerization inhibition accelerator containing a hindered phenol-based compound and a hydroquinone-based compound. The interaction with the polymerization inhibitor and the polymerization inhibition accelerator can suppress the formation of the self-polymerization product in the polymerization step.SELECTED DRAWING: Figure 1
