| titleOfInvention | Brominated rubbers and preparation thereof |
| abstract | When an elastomeric copolymer of a C, or C 5 conjugated diene and an aromatic vinyl compound is brominated as a latex while keeping the uniformity of the latex until the amount of bromine combined with the copolymer reaches 0.5 - 15% by weight, the resulting brominated conjugated diene-aromatic vinyl compound rubber typically contains 3 - 80% by weight of a toluene-insoluble fraction formed by the bromination and typically has a high green strength and a good processability. A vulcanized rubber obtained from such a 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 of the bromination reaction system to 9 or higher, preferably 10 or higher, during the reaction or by adding a nonionic surfactant. When a cationic or nonionic surfactant is used as an emulsifier, regulation of pH is unnecessary. |
