Title (EN) METHOD FOR PRODUCING ACRYLIC RUBBER
(FR) PROCÉDÉ DE FABRICATION DE CAOUTCHOUC ACRYLIQUE
(JA) アクリルゴムの製造方法
Abstract:
(EN) Provided is a method for producing an acrylic rubber, the method being provided with: an emulsion polymerization step for obtaining an emulsified polymer solution by emulsion-polymerizing a monomer for forming the acrylic rubber; an ethylene oxide-based polymer addition step for adding an ethylene oxide-based polymer to the emulsified polymer solution before performing coagulation; and a coagulation process for obtaining a water-containing crumb rubber by adding a coagulating agent to the emulsified polymer solution to coagulate the emulsified polymer solution adjusted to have a temperature of at least 78˚C. According to the present invention, a method for producing an acrylic rubber may be provided, wherein a rubber cross-linked product having excellent water resistance is obtained by the method.
(FR) L’invention fournit un procédé de fabrication de caoutchouc acrylique qui est destiné à fabriquer un caoutchouc acrylique, et qui comporte : une étape de polymérisation en émulsion au cours de laquelle est obtenu un liquide de polymérisation en émulsion par polymérisation en émulsion d’un monomère destiné à former ledit caoutchouc acrylique ; une étape de d’ajout de polymère à base d’oxyde d’éthylène au cours de laquelle un polymère à base d’oxyde d’éthylène est incorporé audit liquide de polymérisation en émulsion avant solidification ; et une étape de solidification au cours de laquelle sont obtenues des granules hydratées par solidification en ajoutant un agent de solidification audit liquide de polymérisation en émulsion ajusté à une température supérieure ou égale à 78°C. Enfin, l’invention permet de fournir un procédé de fabrication de caoutchouc acrylique qui permet d’obtenir un produit réticulé de caoutchouc d’une excellente résistance à l’eau.
(JA) アクリルゴムを製造する方法であって、前記アクリルゴムを形成するための単量体を乳化重合することで、乳化重合液を得る乳化重合工程と、凝固を行う前の前記乳化重合液に、エチレンオキシド系重合体を含有させるエチレンオキシド系重合体添加工程と、78℃以上の温度に調整した前記乳化重合液に、凝固剤を添加して凝固させることで、含水クラムを得る凝固工程と、を備えるアクリルゴムの製造方法を提供する。本発明によれば、耐水性に優れたゴム架橋物を与えるアクリルゴムの製造方法を提供することができる。
