Method for immobilizing ligand or compound having ligand bonded thereto

A ferrite composition containing a spinel ferrite and a small amount of a polyphenylene sulfide as a binder, which can provide a molding product having a higher initial permeability and excellent thermal, flame and arc resistances. The molding product is prepared by molding the composition at an elevated temperature under pressure. The use of a ferrite mixture of particle groups having different particle size distributions within the particle size range of 100.mu. to 5 mm. is preferred.

Ferrite composition having higher initial permeability and process for

A magnetic recording medium comprising a magnetic sheet of domain sized particles of at least one member selected from the group consisting of barium ferrite, strontium ferrite and lead ferrite, dispersed uniformly in an organic binder, and a ferromagnetic plate bonded to one surface with the other surface of the sheet being magnetizable at selected sites with the magnetization being in a direction substantially perpendicular to the surfaces.

Magnetic recording medium

A foam and flame-breakable resin composition comprising a non-inflammable agent, an auxiliary non-inflammable agent, a foaming agent, an ash coagulating agent and a resin system consisting essentially of a blend of a copolymer of ethylene and vinyl acetate having a high melt viscosity with the vinyl acetate content being between 40 to 80 weight percent and the molecular weight being more than 200,000, and polyvinyl chloride in a ratio of copolymer to polyvinyl chloride of 2:8 to 7:3. The composition may be further subjected to vulcanization treatment.

Electron beam cured intumescent coating composition

A method of improving the physical properties, such as workability and impact strength, of ceramics, wherein particles of ceramics are coated with atactic polypropylene, subsequently formed into desired shape under compression and then sintered.

Method for improving the physical properties of ceramics

A self-bonding magnet wire comprising a conductor with a coating thereon, said coating comprising 65 to 95 parts by weight of a copolyamide containing 10 to 50 weight percent .omega.-laurolactam, 35 to 5 parts by weight of a copolyamide containing 70 to 90 weight percent of .omega.-laurolactam, and 5 to 25 parts by weight of a thermoplastic linear polyhydroxypolyetherester resin and process of manufacturing same.
