    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： The present invention provides xanthogen-modified chloroprene rubber that maintains the basic characteristics of conventional chloroprene rubber while exhibiting good dynamic characteristics, and a production method for the xanthogen-modified chloroprene rubber. The xanthogen-modified chloroprene rubber and the production method therefor are characterized in that a molecular terminal of the chloroprene rubber comprises a structure that is represented by formula (1). In the formula, R represents an alkyl group, and x is an integer of 1 or greater.
