Abstract
(EN)
The purpose of the present invention is to provide a resin composition which is suppressed in change of the void fraction of hollow resin particles during molding, and which stably enables the achievement of a lightweight molded body that is suppressed in variation of specific gravity. A resin composition which is characterized by containing 50-95 parts by mass of a thermoplastic elastomer and 5-50 parts by mass of hollow resin particles, and which is also characterized in that: the hollow resin particles have a void fraction of from 50% to 85%; each of the hollow resin particles has a shell that contains a resin; and the resin contains, as polymerizable monomer units, 30-100 parts by mass of a crosslinkable monomer unit and 0-70 parts by mass of a non-crosslinkable monomer unit when the repeating units constituting the resin are taken as 100 parts by mass.

La présente invention vise à fournir une composition de résine dont la fraction de vide des particules de résine creuse n'est pas modifiée durant le moulage et qui permet d'obtenir de manière stable un corps moulé léger dont la gravité spécifique ne varie pas. L'invention concerne une composition de résine qui est caractérisée en ce qu'elle contient 50 à 95 parties en masse d'un élastomère thermoplastique et 5 à 50 parties en masse de particules de résine creuse, et qui est également caractérisé en ce que : les particules de résine creuses ont une fraction de vide de 50 % à 85 % ; chacune des particules de résine creuses a une enveloppe qui contient de la résine ; et la résine contient, en tant qu'unités monomères polymérisables, 30 à 100 parties en masse d'une unité monomère réticulable et 0 à 70 parties en masse d'une unité monomère non réticulable lorsque les unités récurrentes constituant la résine sont prises comme 100 parties en masse.
