摘要： A process for producing a chlorinated rubber which comprises chlorinating a latex or aqueous dispersion of a rubber to prepare a chlorinated rubber cake which weakly to highly acidic, drying the cake by fluidized drying together with a drying medium, and successively drying the resultant predried powder by fluidized drying. Thus, a high-quality chlorinated rubber can be efficiently obtained from the chlorinated rubber cake while attaining satisfactory handleability.
