A perpendicular magnetization film of iron-chromium alloy having an easy magnetization axis perpendicular to a plane of substrate, and the preparation thereof. The perpendicular magnetization film provides a dominant peak corresponding to a lattice constant of 2.07 to 2.08 .ANG. in X-ray diffraction spectrum, and possesses a large saturation magnetization of more than 100 emu/cm.sup.3. The perpendicular thin film can be prepared by depositing iron and chromium on the substrate under vacuum or an atmosphere of argon gas at a low pressure.

Perpendicular magnetization film and the preparation thereof

Composition and method of manufacturing same, wherein a vinyl chloride resin has talc therein in direct contact with vinyl chloride based polymer particles without any intervening material therebetween.

Vinyl chloride resin talc-embedded composition and method of

Vinyl chloride resin composition comprising vinyl chloride series resin and a two stage polymerization product comprising methyl methacrylate or a monomeric mixture containing a major proportion of methyl methyacrylate subjected to emulsion polymerization and then in the presence of the resulting rigid thermoplastic phase an elastomer phase is formed onto the surface of the rigid thermoplastic phase by polymerizing a monomeric mixture containing a major proportion of an acrylic acid ester and/or a methacrylic acid ester, esclusive of methyl methacrylate.

Vinyl chloride resin compositions

Vinyl chloride series resin compositions comprising (a) 90 to 50 parts by weight vinyl chloride series resins and (b) 10 to 50 parts by weight of graft polymers obtained by polymerizing (i) 20 to 65 weight percent butadiene series rubber, (ii) 20 to 50 weight percent vinyl aromatic hydrocarbon, (ii) 10 to 50 weight percent methyl methacrylate, (iii) 2 to 50 weight percent acrylic ester, and (iv) 0 to 40 weight percent acrylonitrile.

Vinyl chloride series resin blend compositions

A method of suspension polymerizing in an aqueous medium vinyl chloride or a mixture of 50% or more vinyl chloride and remainder other monomers copolymerizable therewith in the presence of an oil soluble initiator, a suspension stabilizer and 0.005 to 50 ppm of nitrite, and 10 to 1000 ppm of water soluble metallic salt, the parts being based on the amount of aqueous medium.
