Abstract
(EN) Provided is a technology for improving the dispersion stability of an antioxidant in a chloroprene polymer latex, and improving the heat resistance of the chloroprene polymer latex when the chloroprene polymer latex is dried. This statistical copolymer latex comprises a chloroprene monomeric unit and an unsaturated nitrile monomeric unit, the contained amount of the unsaturated nitrile monomeric unit being 5-20 mass%, wherein the contained amount of the antioxidant as measured by gas chromatography when the statistical copolymer latex is diluted in a tetrahydrofuran solution is 1.0-6.0 mass% with respect to 100 mass% of the statistical copolymer latex, and the antioxidant concentration ratio (surface sample liquid/bottom sample liquid) of liquids sampled from the surface and bottom of the statistical copolymer latex after the statistical copolymer latex has been centrifuged at 14,000 revolutions/min for 20 min is 0.6-1.2.
(FR) L'invention concerne une technologie pour améliorer la stabilité de dispersion d'un antioxydant dans un latex de polymère de chloroprène, et améliorer la résistance à la chaleur du latex de polymère de chloroprène lorsque le latex de polymère de chloroprène est séché. Ce latex de copolymère statistique comprend une unité monomère de chloroprène et une unité monomère de nitrile insaturé, la quantité contenue de l'unité monomère de nitrile insaturé étant de 5 à 20 % en masse, la quantité contenue de l'antioxydant telle que mesurée par chromatographie en phase gazeuse lorsque le latex de copolymère statistique est dilué dans une solution de tétrahydrofurane est de 1,0 à 6,0 % en masse par rapport à 100 % en masse du latex de copolymère statistique, et le rapport de concentration en antioxydant (échantillon de liquide de surface/échantillon de liquide de fond) de liquides échantillonnés à partir de la surface et du fond du latex de copolymère statistique après la centrifugation du latex de copolymère statistique à 14 000 tours/min pendant 20 min est de 0,6 à 1,2.
