摘要:
The invention provides a process for producing a carboxyl-containing polymer composition that allows the possibility of obtaining a carboxyl-containing polymer composition which exhibits excellent dispersibility in water or the like, has a viscosity increasing to a lower degree compared to the viscosity of a neutralized viscous liquid using an additive-free carboxyl-containing polymer, and has a high degree of transparency in a neutralized viscous liquid thereof. A carboxyl-containing polymer composition is obtained by polymerizing a monomer containing an α,β-unsaturated carboxylic acid as a main component in a presence of a polyol (iso)stearic acid ester. A polyol in the polyol (iso)stearic acid ester is a polyol selected from a specific group, and the polyol (iso)stearic acid ester is used in the polymerization in an amount of 0.2 to 7 parts by mass based on 100 parts by mass of the α,β-unsaturated carboxylic acid.

The present invention provides a lubricating resin composition for personal care, wherein the composition not only maintains its excellent lubricity and roughness-resistant property under a wet condition even during repeated use thereof, but also represents a low swelling ratio and no slimy feeling under a wet condition. The lubricating resin composition for personal care of the present invention comprises 100 parts by mass of a water-absorbent modified polyalkylene oxide and 25 to 500 parts by mass of a low-melting point polyamide resin.

[Problems] To provide a carboxyl group-containing polymer composition having excellent dispersibility in water or the like, and a neutralized viscous liquid of which has a low viscosity and high transparency. [Solving Means] A carboxyl group-containing polymer composition containing at least one compound selected from the group consisting of (1) a fatty acid A and (2) a fatty acid ester formed between a fatty acid B and a monohydric alcohol having 1 to 22 carbon atoms, in an amount of from 0.05 to 5 parts by mass, based on 100 parts by mass of a carboxyl group-containing polymer, wherein the carboxyl group-containing polymer is obtainable by copolymerizing an α,β-unsaturated carboxylic acid and a compound having two or more ethylenically unsaturated groups.
摘要:
A gelling agent capable of turning an electrolyte solution for an alkaline battery into a gel, which is less likely to cause syneresis, is composed of particles of a carboxyl group-containing polymer, and a 0.1% by weight aqueous solution has a viscosity of at least 3,000 mPa·s at a pH of 7. The particles of a carboxyl group-containing polymer are normally obtainable by polymerizing a polymerizable material containing α,β-unsaturated carboxylic acids, for example, a polymerizable material containing α,β-unsaturated carboxylic acids and a compound having two or more ethylenically unsaturated groups as a cross-linking agent, in an inert solvent which dissolves the α,β-unsaturated carboxylic acids but does not dissolve particles of a carboxyl group-containing polymer. The above-mentioned viscosity is achieved by adjusting the balance among the concentration of the α,β-unsaturated carboxylic acids, the concentration of a cross-linking agent and a polymerization temperature during polymerization.
