Title (EN) RUBBER-MODIFIED AROMATIC VINYL RESIN COMPOSITION AND PROCESS FOR THE PRODUCTION THEREOF
(FR) COMPOSITION DE RESINE VINYLIQUE AROMATIQUE MODIFIEE AU CAOUTCHOUC ET SON PROCEDE DE PRODUCTION
Abstract:
(EN) A rubber-modified aromatic vinyl resin composition having the following characteristics: (a) the composition contains 4 to 20 % by weight of a rubbery polymer; (b) the rubbery polymer is dispersed in an aromatic vinyl polymer in the form of particles having a weight-mean diameter of 0.4 to 0.8 $g(m)m; (c) the 5 % value of the weight-based diameter distribution of the particles is 1.0 $g(m)m or below and the 95 % value thereof is 0.2 $g(m)m or above; (d) the ratio of the toluene inslubles contained in the composition to the rubber component contained therein is 1.0 to 2.5; and (e) the composition contains 0.005 to 0.5 % by weight of a silicone oil and, if necessary, 0.0002 to 0.03 % by weight of a fluorine compound oil. This composition is well balanced between impact strength and stiffness, and is excellent in gloss.
(FR) Composition de résine vinylique aromatique modifiée au caoutchouc, présentant les caractéristiques suivantes: (a) contient 4 à 20 % en poids d'un polymère caoutchouteux; (b) ledit polymère est dispersé dans un polymère vinylique aromatique sous la forme de particules présentant un diamètre moyen en poids de 0,4 à 0,8 $g(m)m; (b) 5 % de la répartition du diamètre en poids des particules est de 1,0 $g(m)m ou moins et 95 % de celle-ci est de 0,2 $g(m)m ou plus; (d) le rapport entre les substances insolubles dans le toluène, contenues dans la composition, et le composant caoutchouteux de celle-ci est de 1,0 pour 2,5; et (e) la composition contient 0,005 à 0,5 % en poids d'une huile silicone et, si nécessaire, 0,0002 à 0,03 % en poids d'une huile composée fluorée. Cette composition est bien équilibrée pour ce qui concerne sa résistance à l'impact et sa rigidité, et présente un brillant de grande qualité.
