摘要： The invention provides a foamed body of a chlorine-containing synthetic resin of high expansion with extremely low bulk density still retaining very fine and uniform cellular structure. Different from conventional foamed bodies of polyvinyl chloride resins, the inventive foamed body is formed of a chlorinated polyvinyl chloride resin so that the foamed body has excellent heat resistance. The method for the preparation of the foamed resin comprises: preparing a resin composition comprising a chlorinated polyvinyl chloride resin or a mixture thereof with a polyvinyl chloride resin, a foam conditioning resin, e.g. an acrylic resin or a styrene-based resin, and a cell uniformnizing agent, e.g. a heat-decomposable blowing agent or an inorganic fine powder; supplying the resin composition to the cylinder of an extruder machine; uniformly impregnating the at leat partly molten resin composition in the cylinder with a volatilizable blowing agent by pressurization; and shaping the resin composition by extruding out of the extruder with simultaneous expansion by foaming.

摘要： The invention provides a very simple but effective means for preventing surface oxidation of fine metal powders by coating the metal powder with an organic dye. This method of surface-oxidation prevention is particularly useful for the preparation of a so-called plastic magnet which is prepared by uniformly blending a dye-coated fine powder of a magnetic alloy such as a rare earth-cobalt. based permanent magnet with a thermoplastic resin such as a nylon or polyphenylene sulfide resin followed by molding the resin- powder blend into a magnet form. In addition to the remarkably improved magnetic properties of the thus prepared plastic magnets as a result of high loading and absence of degradation by oxidation, the danger of spontaneous ignition of the magnet powder in molding can be eliminated almost completely. Surface treatment of the dye-coated magnet powder with a silicone fluid gives further improved results.

摘要： A polyvinyl chloride resin composition which is highly heat-resistant as a result of compounding with an organic tin mercaptide compound as a heat stabilizer is still free from the problem of the unpleasant odour emitted by the mercaptide compound as a result of compounding a specific deodorizing agent therewith, so that the composition is suitable as a moulding resin composition for food containers. The deodorizing agent is a diterpenic acid such as abietic acid or a rosin, which latter is a crude mixture of several kinds of diterpenic acids obtained as a natural product.

摘要： 57 The plastic magnet composition provided by the invention comprises a thermoplastic resin as a binder and a powder of a metallic or alloy-type magnet which is coated on the particle surface with a phosphorus-containing compound having at least one phosphorus-to-oxygen linkage in a molecule such as phosphoric acid and related compounds. By virtue of the surface coating, the magnet powder is freed from the degradation by air oxidation and the danger of ignition in the molding process so that plastic magnets of high performance can be readily manufactured with safety. The advantages of the coating layer are further increased when the coating layer is formed of a combination of the phosphorus-containing compound and an organic dye compound. An overcoating on the thus coated magnet powder with an organo-polysiloxane has an effect of increased lubricity.
