Abstract
(EN)
Provided is a latex containing: butyl rubber; a nitrile group-containing conjugated diene copolymer; and water, wherein the weight ratio of the butyl rubber to the nitrile group-containing conjugated diene copolymer is 85:15 to 10:90. According to the present invention, it is possible to provide a latex which has a short gelation time, and with which a molded body having excellent oil resistance can be obtained.
(FR)
L'invention concerne un latex contenant : du butylcaoutchouc ; un copolymère de diène conjugué contenant un groupe nitrile ; et de l'eau, le rapport en poids entre le butylcaoutchouc et le copolymère de diène conjugué contenant un groupe nitrile étant compris entre 85:15 et 10:90. La présente invention permet d'obtenir un latex qui a un temps de gélification court, et au moyen duquel un corps moulé ayant une excellente résistance à l'huile peut être obtenu.
