    摘要: The present invention provides aqueous dispersion slurry of inorganic particles which is so stable as not to increase in viscosity, gel or sediment even if stored for a long time and therefore can be used as raw materials for, for example, cosmetics, paint, coating materials and lapping slurry for semiconductor wafers, and production method of such aqueous dispersion slurry. The aqueous dispersion slurry according to the present invention has the number of particles whose a particle diameter of 1.3 .mu.m or more is 180,000 or less per mL in terms of 30 wt % in concentration, and the average particle diameter thereof is in a range of 0.05-0.9 .mu.m. The number of particles having aparticle diameter of 1.3 .mu.m or more is counted by using Particle Sensor KS-60, which is a light extinction type sensor for detecting particles, and Particle Counter KL-11, which is a particle counter, both of which made by the same manufacturer, Rion Electro Corp. The average particle diameter is measured by using Laser Particle Analyzer System Par-III made by Otsuka Denshi Co., Ltd.

    摘要: A process for the preparation of highly crosslinked polymer particles from polymerizable vinyl monomers comprising 15% by weight or more of a crosslinking vinyl monomer. The process comprises: providing an organic solvent, a mixture of organic solvents, or a mixture of at least one organic solvent and water which can dissolve the polymerizable vinyl monomers but cannot dissolve the polymer which is produced by the polymerization of the polymerizable vinyl monomers, the solubility in water of the polymerizable vinyl monomer being not more than 30% by weight, dispersing the polymerizable vinyl monomers into the organic solvent, the mixture of organic solvents, or the mixture of the at least one organic solvent and water, and polymerizing the polymerizable vinyl monomers in the presence of a dispersion stabilizer and a radical polymerization initiator. The crosslinked polymer particles have a comparatively uniform particle size within the particle size range of 0.1-10 .mu.m. They are useful as a slip property improver for plastic films, a spacer for liquid crystal display devices, a carrier for chromatography, and a standard sample for microscopic examination.

    摘要: It is an object of the invention to provide an aqueous dispersion for CMP that produces no scratches on polishing surfaces and that polishes with an adequate rate, when used for polishing of copper and the like. The aqueous dispersion of the invention contains water and polymer particles composed of a polymer with a specific functional group, and it may also contain a complexing agent, a compound that forms a passivation film on polishing surfaces and/or an oxidizing agent. The specific functional group is a functional group that can react with the metals of polishing surfaces or that can form a cation, and it is preferably selected from among amino, pyridyl and acrylamide groups. The polymer can be obtained using a initiator and/or monomer possessing the specific functional group. The polymer may also have a crosslinked structure.
