A fishing line is produced by forming a monofilament by subjecting a resin composition (C) containing 90 to 99.3% by weight of a polyamide resin (A) and 0.7 to 10% by weight of a silicone compound (B) having a number average molecular weight of 100,000 to 2,000,000 to melt-spinning and then drawing. This method can provide a fishing line which is excellent in abrasion resistance and also excellent in visibility. In this method, it is preferable to conduct melt-kneading of a part of the polyamide resin (A) with the silicone compound (B) in advance, adding of the residual polyamide resin (A) and further melt-kneading, subsequent melt-spinning, and drawing at a draw ratio of from 4 to 7.

Fishing line and method for production thereof

A method for preparing a polyorganosiloxane which is sold at 25&#xb0; C. and has RSiOunits wherein Ris a hydrocarbon group having 1 to 10 carbon atoms and SiOunits, said method comprising the steps of:

Method for preparing solid polyorganosiloxane

A surface-treated powder powder which is surface-treated with an acrylic/silicone copolymer having at least one hydrolyzable silyl group in the molecule, and a cosmetic material containing this powder. The surface-treated powder of this invention preferably contains 0.1-30 wt parts of the acrylic/silicone copolymer relative to 100 wt parts of the powder prior to surface treatment. The acrylic/silicone copolymer preferably comprises a trunk polymer comprising an acrylic polymer, and a branched polymer comprising an organic polysiloxane. The surface activity of the surface-treated powder of this invention is very well blocked, and it has excellent water resistance and sebum resistance. In addition, the cosmetic material of this invention containing this surface-treated powder has good cosmetic lasting properties, and is highly stable over time.

Surface-treated powder and cosmetic preparation

A dimethylpolysiloxane composition comprising at least two dimethylpolysiloxanes selected from dimethylpolysiloxanes represented by formula (1) or formula (2),wherein m is an integer with 0&#x2266;m&#x2266;10 and n is an integer with 3&#x2266;n&#x2266;10, one of said at least two dimethylpolysiloxanes is dodecamethylpentasiloxane contained in an amount of 15 to 95 wt % based on a total weight of the composition, and the composition has a moisture content of at most 50 ppm based on the total weight of the composition.

Dimethylpolysiloxane composition

The invention discloses an efficient method for removing a wallpaper sheet by peeling off a wall body surface to which the wallpaper sheet is adhesively bonded as well as a wallpaper remover solution used in the method for wetting the wallpaper sheet to facilitate peeling. The remover solution contains, as the essential ingredients, (A) a silicone-based surface active agent which is an organopolysiloxane modified with polyoxyalkylene or polyhydric alcohol residues and (B) a moisturizing agent which is typically a polyhydric alcohol or a alkoxyalkanol compound each in a specified concentration of 40-80% by weight, the balance being water as the solvent.

Silicon compound, and a makeup containing this compound

An organic silicone resin powder having a tabular shape the aspect ratio of which is greater than about 1 and comprising a copolymer produced by polymerization reaction between an organopolysiloxane containing at least one reactive group and at least one kind of monomer or oligomer capable of reacting to said reactive group, which can fully achieve its excellent effects when mixed in cosmetic materials, waxes and coating colors, especially in cosmetic materials.

Organic silicone resin powder

Disclosed is a method for the preparation of an organopolysiloxane-grafted graft copolymer of a carbon-carbon backbone chain structure which is free from the troubles due to emission of an irritative odour and instability in storage. The method comprises the steps of copolymerizing a (meth)acryloxyalkyl-terminated organopolysiloxane compound with (meth)acrylic acid or an alkyl (meth)acrylate, optionally, together with a long chain-alkyl (meth)acrylate and/or a (meth)acryloxy-terminated polyoxyalkylene compound in a solution polymerization process to give a polymer solution and subjecting the polymer solution to a catalytic hydrogenation treatment so as to completely eliminate any unpolymerized acrylic compounds.

Organopolysiloxane-grafted copolymeric compound

Disclosed is a novel method for the preparation of an organo-polysiloxane-grafted polysaccharide compound which is particularly useful as an additive ingredient in various types of cosmetic and toiletry preparations. The method utilizes a reaction between epoxy groups of a diorganopolysiloxane, e.g., dimethylpolysiloxane, terminated at a single molecular chain end with a 2-(3,4-epoxycyclohexyl)ethyl group and carboxyl groups in a carboxyl group-containing polysaccharide compound such as hydroxypropyl methyl cellulose phthalate and hydroxypropyl methyl cellulose acetate succinate dissolved in an organic solvent. The reaction proceeds efficiently without addition of any catalytic compounds almost quantitatively under moderate reaction conditions.

Organopolysiloxane-grafted polysaccharide compound

Disclosed is a water repellent for fibers, comprising an acryl-silicone graft copolymer which is prepared by a radical copolymerization reaction of an organopolysiloxane compound containing one radical polymerizable group with radical polymerizable monomers including an acrylate, a methacrylate or a mixture thereof as a main member.

Agent for water-repellent treatment of fibers

A hydrolyzate resulting from co-hydrolysis of a perfluoroalkyl group-containing organic silicon compound and a hydrolyzable group-containing methylpolysiloxane compound in a hydrophilic solvent is blended with an organopolysiloxane and a strong acid to constitute a water repellent composition which is effective for imparting water repellency and facilitating falling of water droplets and thus imparting excellent water repellency and stain-proofness to a surface of an article treated therewith.
