Title (EN) METHOD FOR PRODUCING NITRILE GROUP-CONTAINING COPOLYMER RUBBER
(FR) PROCÉDÉ DE PRODUCTION DE CAOUTCHOUC COPOLYMÈRE CONTENANT UN GROUPE NITRILE
(JA) ニトリル基含有共重合体ゴムの製造方法
Abstract:
(EN) Provided is a method for producing a nitrile group-containing copolymer rubber by copolymerizing a monomer mixture containing an α,β-ethylenic unsaturated nitrile monomer and a conjugated diene monomer, wherein the Mooney viscosity (ML1+4, 100°C) of the copolymer at a point when the polymerization conversion rate is 60% is set in the 30-60 range, polymerization is performed until the polymerization conversion rate reaches 85% or higher, and a nitrile group-containing copolymer rubber having a Mooney viscosity (ML1+4, 100°C) of 85-150 is obtained.
(FR) L'invention concerne un procédé de production d'un caoutchouc copolymère contenant un groupe nitrile par copolymérisation d'un mélange de monomères contenant un monomère de nitrile insaturé α,β-éthylénique et un monomère de diène conjugué, la viscosité Mooney (ML1 + 4, 100 °C) du copolymère en un point lorsque le taux de conversion de polymérisation est de 60 % étant définie dans la plage de 30 à 60, la polymérisation étant effectuée jusqu'à ce que le taux de conversion de polymérisation atteigne 85 % ou plus, et un caoutchouc copolymère contenant un groupe nitrile ayant une viscosité Mooney (ML1 + 4, 100 °C) de 85 à 150 étant obtenu.
(JA) α,β-エチレン性不飽和ニトリル単量体および共役ジエン単量体を含む単量体混合物を共重合させることにより、ニトリル基含有共重合体ゴムを製造する方法であって、重合転化率が60%の時点における共重合体のムーニー粘度(ML1+4,100℃)を30~60の範囲とし、前記重合転化率が85%以上になるまで共重合を行い、ムーニー粘度(ML1+4,100℃)が85~150の前記ニトリル基含有共重合体ゴムを得るニトリル基含有共重合体ゴムの製造方法を提供する。
