butadiène : Hydrocarbure diénique de formule C4H6, dont il existe deux isomères, le butadiène-1,2 [de formule] CH2=C=CH-CH3, et le butadiène-1,3, CH2=CH-CH=CH2. 11, record 1, French, - buta%2D1%2C3%2Ddi%C3%A8ne

Seul l'isomère 1,3 du butadiène est important. Prototype des diènes 1,3, il en a toutes les propriétés. Industriellement, celles-ci sont mises à profit pour fabriquer des polymères ou des copolymères (avec le styrène, l'acrylonitrile ou l'isobutène), qui sont tous des élastomères. Il joue aussi un rôle important comme intermédiaire dans la synthèse du Nylon. 11, record 1, French, - buta%2D1%2C3%2Ddi%C3%A8ne

The cis-isomer, which is similar to natural rubber, is used in tire treads due to its abrasion and crack resistance and low heat build-up. Large quantities are also used as blends in SBR rubber. The trans-isomer resembles gutta percha and has limited utility. Liquid polybutadiene, which is sodium-catalyzed, has specialty uses as a coating resin. It is cured with organic peroxides. 4, record 3, English, - polybutadiene

Le polybutadiène est souvent utilisé en mélange avec le caoutchouc naturel, auquel il confère une bonne résistance aux basses températures. Il est également associé au caoutchouc naturel et à divers élastomères synthétiques dans la fabrication de l'ébonite. C'est cependant par ses copolymères que le butadiène est essentiel : il donne avec le nitrile acrylique des copolymères appelés «caoutchoucs nitriles»; avec le styrène, des copolymères d'un très grand intérêt [...]; en association avec l'acrylonitrile et le styrène, des terpolymères appelés ABS. 3, record 3, French, - polybutadi%C3%A8ne
