Abstract
Provided is a lubricating composition for inhibiting plugging including a base oil and any one selected from a fatty acid and an emulsifier, with the lubricating composition forming a single phase even when a carboxylic acid-based monomer is introduced with respect to the base oil. The lubricating composition suppresses plugging occurring in a process of preparing a copolymer derived from the carboxylic acid-based monomer. In addition, also provided is a method of inhibiting plugging using the lubricating composition for inhibiting plugging.
Claims9
A lubricating composition for inhibiting plugging of equipment in the polymerization of ethylene with an unsaturated carboxylic acid monomer capable of a chain polymerization reaction, comprising:
- a base oil;
- and
- an emulsifier selected from the group consisting of a cationic polymer having a polyethyleneimine group and a phosphonate group;
- and a polyolefin-based polymer having a polyisobutylene succinimide (PIBSI) group,
- wherein the lubricating composition forms a single phase in a temperature range of 20 to 85° C. and suppresses self-polymerization of the unsaturated carboxylic acid monomer when the unsaturated carboxylic acid monomer is introduced with respect to the base oil,
- wherein the emulsifier is included at 1 to 15 wt %, with respect to the total lubricating composition, and
- wherein the unsaturated carboxylic acid monomer is selected from the group consisting of an acrylic acid monomer and a methacrylic acid monomer.
