  A sulfur-modified chloroprene rubber having a functional group A represented by General Formula (A) below and positioned at a molecular terminal, in which a mass ratio B/A of a content of a functional group B represented by General Formula (B) below and positioned at a molecular terminal with respect to a content of the functional group A is 6.00 or less, and a total amount of the functional group A and the functional group B is 0.10 to 0.60% by mass. (In the formula, Ra1 and Ra2 each independently represent a hydrogen atom, a halogen atom, a hydroxy group, an alkoxy group, a carboxy group, a carboxylate group, a cyano group, an alkyl group which may have a substituent, or an arylthio group which may have a substituent, and Ra1 and Ra2 may bond with each other to form a ring which may have a substituent.) (In the formula, Rb represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms which may have a substituent.)

  [FR] L'invention porte sur des dérivés sulfénamides du 2-mercapto benzothiazole 4-alkyl substitué (4m-MBT) utilisés comme accélérateurs dans des compositions de caoutchouc vulcanisables. Les dérivés précités permettent de conférer des propriétés améliorées de résistance à la réversion et de stabilisation du module d'élasticité et de la dureté à des composés pour pneus vulcanisés au soufre principalement à base de caoutcouch naturel ou de mélanges de caoutchouc naturel et de polybutadiène (BR) et de caoutchouc styrène butadiène (SBR) dans lesquels le caoutchouc naturel constitue le composant principal, améliorant de la sorte les performances globales des pneus, ainsi que leur sécurité de roulement et leur durée de vie utile.
