摘要： When an elastomeric copolymer of a C.sub.4 or C.sub.5 conjugated diene and an aromatic vinyl compound is brominated in latex while keeping the uniformity of the latex until the amount of bormine combined with the copolymer reaches 0.5-15% by weight, the resulting brominated conjugated diene-aromatic vinyl compound rubber contains 3-80% by weight of a toluene-insoluble fraction formed by the bromination and has a high green strength and a good processability. A vulcanized rubber obtained from said brominated rubber has a high modulus of elasticity and a high tensile strength. When an anionic surfactant is used as an emulsifier, the uniformity of the above-mentioned latex can be kept by adjusting the pH value of the bromination reaction system to 9 or highter, preferably 10 or higher, during the reaction or by auxiliarily adding a nonionic surfactant. When a cationic or nonionic surfactant is used as an emulsifier, regulation of pH is unnecessary.
