摘要： A chloroprene rubber composition containing 100 parts by mass of a chloroprene-based rubber, 0.5 to 5.0 parts by mass of a sulfur-based compound represented by General Formula (1) below, and more than 0 parts by mass and 2.0 parts by mass or less of a xanthogen disulfide compound represented by General Formula (2) below.
[In the formula, R 1 represents a hydrogen atom, a hydroxyl group, or an alkyl group having 1 to 8 carbon atoms, and R 2 and R 3 each independently represent a hydrogen atom or an alkyl group having 1 to 8 carbon atoms.]
[In the formula, R 4 and R 5 each independently represent a hydrogen atom or an alkyl group having 1 to 8 carbon atoms.]-

摘要： 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 12.00 or less, and a total amount of the functional group A and the functional group B is 0.10 to 1.00% by mass.
(In the formula, R a1 and R a2 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 R a1 and R a2 may bond with each other to form a ring which may have a substituent.)
(In the formula, R b1 and R b2 each independently represent an alkyl group which may have a substituent or an aryl group which may have a substituent.)-

摘要： Provided is a laminate having elastomer layers tightly bonded to each other. The laminate according to the present invention 1 has an acrylic elastomer layer 11 and a fluorine elastomer layer 12 that are bonded to each other. The acrylic elastomer layer 11 is made of an acrylic elastomer composition having an epoxy group-containing acrylic elastomer and an onium salt added and the fluorine elastomer layer 12 is made of a fluorine elastomer composition having a fluorine elastomer and a polyol crosslinking agent added. In the laminate 1, the elastomer layers are bonded tightly to each other even without any surface treatment.
