Title
(EN) ORGANIC FINE PARTICLE
(FR) PARTICULE FINE ORGANIQUE
(JA) 有機微粒子
Abstract
(EN) Provided is an organic fine particle containing a core polymer and a shell polymer. The Tg value or melting point of the core polymer is 15°C or higher. The contact angle with water of the core polymer is 100° or more. All monofunctional monomers that constitute the core polymer are hydrophobic core monomers, homopolymers of which have a contact angle with water of 100° or more. The Tg value or melting point of the shell polymer is lower than the Tg value or melting point of the core polymer. The contact angle with water of the shell polymer is less than 100°. All monofunctional monomers that constitute the shell polymer are water-insoluble shell monomers, homopolymers of which are water-insoluble. Also provided is a water-repelling agent composition which is obtained using the organic fine particle and can impart a substrate with excellent water repellency.
(FR) L'invention concerne une particule fine organique contenant un polymère de cœur et un polymère d'écorce. La valeur Tg ou le point de fusion du polymère de cœur est supérieur(e) ou égal(e) à 15 °C. L'angle de contact du polymère de cœur avec l'eau est supérieur ou égal à 100°. Tous les monomères monofonctionnels qui constituent le polymère de cœur sont des monomères de cœur hydrophobes, dont les homopolymères ont un angle de contact avec l'eau supérieur ou égal à 100°. La valeur Tg ou le point de fusion du polymère d'écorce est inférieur(e) à la valeur Tg ou au point de fusion du polymère de cœur. L'angle de contact du polymère d'écorce avec l'eau est inférieur à 100°. Tous les monomères monofonctionnels qui constituent le polymère d'écorce sont des monomères d'écorce insolubles dans l'eau, dont les homopolymères sont insolubles dans l'eau. L'invention concerne également une composition d'agent hydrofuge qui est obtenue à l'aide de la particule fine organique et qui peut conférer à un substrat un excellent effet déperlant.
