Abstract
A chlorosulfonated polyethylene latex, which is safe for living bodies and the environment and can be used as a latex component in a resorcin-formalin-latex adhesive, contains an aqueous dispersion medium, chlorosulfonated polyethylene, and an emulsifying agent of a polyoxyalkylene alkyl ether sulfate of formula (I) below and a fatty acid salt. The latex is excellent in standing stability and mechanical stability. In formula (I), R1, R2, n, and M represent an alkyl group of 6 to 20 carbon atoms, hydrogen or a methyl group, an integer of 2 to 40, and an alkali metal, respectively.R1—O—(CH2CHR2—O)n—SO3M (I)
