Title
(EN) ACRYLIC RUBBER COMPOSITION AND RUBBER CROSSLINKED PRODUCT
(FR) COMPOSITION DE CAOUTCHOUC ACRYLIQUE ET PRODUIT RÉTICULÉ EN CAOUTCHOUC
(JA) アクリルゴム組成物およびゴム架橋物
Abstract
(EN) Blending to improve crosslinking characteristics is required even for conventional acrylic rubber because properties other than the crosslinking characteristics must be changed when acrylic rubber is modified, and the present invention addresses the problem of providing an acrylic rubber composition having excellent crosslinking characteristics. It was discovered that the problem can be solved by containing a compound having a polyalkylene oxide skeleton in an acrylic rubber composition.
(FR) Le mélange pour améliorer les caractéristiques de réticulation est nécessaire même pour un caoutchouc acrylique classique parce que les propriétés autres que les caractéristiques de réticulation doivent être modifiées lorsque le caoutchouc acrylique est modifié, et la présente invention aborde le problème de la fourniture d'une composition de caoutchouc acrylique ayant d'excellentes caractéristiques de réticulation. Il a été découvert que le problème peut être résolu par l'ajout d'un composé ayant un squelette d'oxyde de polyalkylène dans une composition de caoutchouc acrylique.
(JA) アクリルゴムを改良した場合には、架橋特性以外の物性を変更する必要があるため、従来のアクリルゴムに対しても、架橋特性を向上させるための配合が求められており、架橋特性に優れたアクリルゴム組成物を提供することを課題とする。 アクリルゴム組成物にポリアルキレンオキシド骨格を有する化合物を含有することにより、上記の課題を解決できることを見出した。
