POLISHING MATERIAL - JAPAN SYNTHETIC RUBBER CO LTD

Title:

POLISHING MATERIAL

Document Type and Number:

Japanese Patent JP3521560

Kind Code:

B2

Abstract:

PURPOSE: To obtain a polishing material to be used in finishing operations for the high-level, finished planar accuracy required for magnetic heads or glass fibers, etc., by providing the surface of a substrate with a layer containing a crosslinked polymer particles obtained by polymerizing a crosslinkable monomer having plural groups each containing polymerizable double bond.
CONSTITUTION: This polishing material is obtained by providing the surface of a substrate with crosslinked polymer particles each 0.01-2μm in average diameter obtained by polymerizing ≥5 pts.wt. of a crosslinkable monomer having at least two groups each containing polymerizable double bond. The crosslinkable monomer is e.g. divinylbenzene, polyethylene glycol diacrylate, 1,3-butylene glycol acrylate.
