METHOD FOR PREVENTING STUCKING OF ISOBUTYLENE BLOCK COPOLYMER PELLET

摘要

PROBLEM TO BE SOLVED: To provide a method for preventing the stucking of isobutylene block copolymer pellets during the production, transportation and processing of the pellets. SOLUTION: The method for preventing the stucking of the pellets of an isobutylene block copolymer produced by polymerizing isobutylene and an aromatic vinyl compound comprises the application of a lubricant such as inorganic powder lubricant, fatty acid amide, fatty acid ester and metallic soap to the pellets of the isobutylene bock copolymer by dispersing the polymer pellets in a solution containing the lubricant and removing water from the surface of the pellet.
