Although polyolefin elastomers are widely employed commodity polymers, there are shortcomings of this class of polymers for certain applications. For example, the rheological properties of some polyolefin elastomers may be insufficient to provide the green strength or low shear viscosity necessary to form stable foams, or to provide sufficient viscosity modification effects when present in a solvent. Cationomeric modification of polyolefin elastomers may alleviate these difficulties. Such polyolefin elastomers may feature a random cationomeric polyolefin copolymer comprising at least a first monomer and a second monomer, in which the first monomer is a neutral monomer and the second monomer has a side chain bearing a cationic moiety. The polyolefin elastomers may be present in foamed polyolefin compositions comprising a gas component and/or in liquid compositions comprising a solvent in which the polyolefin elastomer is dissolved.

The invention relates to a composition comprising classic bis-ureas and bis-ureas functionalised by macromolecular chains, said bis-ureas including complementary spacers of the aryl type, the mixture of said bis-ureas in a solvent leading to a stable physical gel. The invention also relates to a method for producing said composition and to the use of said composition as an organogelator, alone or in a cosmetic preparation, an ink, a fuel or a lubricant, especially of a motor vehicle.

The purpose of the present invention is to provide a carbon fiber bundle for resin reinforcement purposes, which is produced using a sizing agent that can exert satisfactory interface adhesiveness to both of a carbon fiber bundle and a thermoplastic resin in the production of a carbon-fiber-reinforced thermoplastic resin, and which has satisfactory emulsion stability. One embodiment of the present invention is a carbon fiber bundle for resin reinforcement purposes, which comprises a carbon fiber bundle and a polymer adhered onto the carbon fiber bundle, wherein the polymer is produced by binding an acid-modified polyolefin having a polyolefin structure and an acidic group in the molecular structure thereof to a hydrophilic polymer having a weight average molecular weight (Mw) of 450 or more, and wherein the ratio of the mass of the polyolefin structure to the mass of the acidic group in the acid-modified polyolefin is 100:0.1 to 100:10, the ratio of the mass of the acid-modified polyolefin to the mass of the hydrophilic polymer is 100:1 to 100:100, and the content of the polymer in the carbon fiber bundle for resin reinforcement purposes is 0.1 to 8.0 mass % inclusive.
