| titleOfInvention | Method for preparing hydrogenated copolymer from conjugated diene hydrogenated latex |
| abstract | The invention provides a method for preparing hydrogenated copolymer by conjugated diene hydrogenation latex, which comprises the following steps: mixing part of the conjugated diene rubber latex with a Holveda-Grubbs II catalyst to obtain a mixture A; mixing the residual conjugated diene rubber latex, the mixture A and a compound additive to obtain a mixture B; the composite auxiliary agent is selected from two or more of sodium oleate, potassium oleate, tetradecenyl sodium sulfonate, tetradecenyl potassium sulfonate, linear alkyl sulfate and alkyl betaine; introducing nitrogen into the mixture B to perform stirring and degassing treatment, and then continuing stirring treatment to obtain a mixture C; and (3) heating the mixture C, introducing hydrogen, and carrying out hydrogenation reaction to obtain a hydrogenated copolymer. Through a batch-adding mixing mode, specific composite auxiliaries are introduced, nitrogen is degassed and then stirred, selective hydrogenation of conjugated diene is achieved, the using amount of a catalyst is reduced, a product with a high hydrogenation degree is obtained, the reaction rate is accelerated, and the catalytic efficiency is improved. |
