Abstract:
(EN) Provided is a carboxyl group-containing polymer composition which has little odor and excellent dispersibility in water, and which additionally has excellent transparency and excellent thickening properties for alcohol gels. A carboxyl group-containing polymer composition according to the present invention contains: a carboxyl group-containing polymer (A) which is a copolymer of a monomer that contains an α,β-unsaturated carboxylic acid (a-1) and a compound (a-2) that has at least two ethylenically unsaturated groups in each molecule; and a nonionic surfactant (B). An alcohol gel A prepared by the process described below has a viscosity of 5,000 mPa·s or more at 25°C; and the alcohol gel A has a light transmittance of 95% or more at a wavelength of 425 nm. (Preparation of alcohol gel A) First, 0.75 part by mass of the carboxyl group-containing polymer composition, 51.70 parts by mass of an ion exchange water and 96.0 parts by mass of ethanol are uniformly mixed with each other. Subsequently, an ethanol solution of triethanolamine having a concentration of 50% by mass is added thereto until the pH reaches 7.0, and the resulting mixture is stirred until the mixture becomes uniform, thereby preparing an alcohol gel A.
(FR) L'invention concerne une composition de polymère contenant un groupe carboxyle, qui est peu odorante et qui présente une excellente dispersibilité dans l'eau, et qui présente en outre une excellente transparence et d'excellentes propriétés épaississantes pour des gels alcooliques. Une composition de polymère contenant un groupe carboxyle selon la présente invention contient : un polymère contenant un groupe carboxyle (A) qui est un copolymère d'un monomère qui contient un acide carboxylique α,β-insaturé (a-1) et un composé (a2) qui a au moins deux groupes à insaturation éthylénique dans chaque molécule ; et un tensioactif non ionique (B). Un gel alcoolique A préparé selon le procédé décrit ci-dessous présente une viscosité à 25 °C supérieure ou égale à 5 000 mPa·s ; et le gel alcoolique A présente une transmittance de lumière à une longueur d'onde de 425 nm supérieure ou égale à 95 %. Le procédé de préparation du gel alcoolique A consiste d'abord à mélanger uniformément les unes aux autres 0,75 partie en masse de la composition de polymère contenant un groupe carboxyle, 51,70 parties en masse d'une eau à échange d'ions et 96,0 parties en masse d'éthanol. Ensuite, une solution éthanolique de triéthanolamine ayant une concentration de 50 % en masse est ajoutée au mélange jusqu'à ce que le pH atteigne 7,0, et le mélange obtenu est agité jusqu'à ce qu'il devienne uniforme, ce qui permet de préparer un gel alcoolique A.
(JA) 臭気が少なく、水への分散性に優れ、さらに、アルコールゲルの増粘性及び透明性に優れたカルボキシル基含有重合体組成物を提供する。 本発明のカルボキシル基含有重合体組成物は、α,β-不飽和カルボン酸(a-1)及び分子内にエチレン性不飽和基を少なくとも2個有する化合物(a-2)を含む単量体の共重合体であるカルボキシル基含有重合体(A)と、ノニオン性界面活性剤(B)とを含む、カルボキシル基含有重合体組成物であって、 下記の方法で調製されるアルコールゲルAの25℃における粘度が、5000mPa・s以上であり、 前記アルコールゲルAの波長425nmの光の透過度が、95%以上である。 (アルコールゲルAの調製) 前記カルボキシル基含有重合体組成物0.75質量部と、イオン交換水51.70質量部と、エタノール96.0質量部とを均一に混合する。次に濃度50質量%のトリエタノールアミンのエタノール溶液をpHが7.0となるまで添加し、均一となるまで攪拌することで、アルコールゲルAを調製する。
