Claims (2)

1. Галогенированные бутилкаучуки, отличающиеся тем, что они содержат 0,5 2,5% галогена, а также больше 0,7 мол. % остаточных непрогалогенированных двойных связей и 1,0 - 2,2 вес.% агентов, контролирующих антиагломерацию и вулканизацию в расчете на общее количество галогенируемого каучука.1. Halogenated butyl rubbers, characterized in that they contain 0.5 to 2.5% halogen, and also more than 0.7 mol. % residual non-halogenated double bonds and 1.0 to 2.2% by weight of anti-agglomeration and vulcanization control agents based on the total amount of halogenated rubber. 2. Способ получения галогенированных бутилкаучуков по п. 1, отличающийся тем, что бутилкаучуки, содержащие 1,0 - 2,2 вес.% (в расчете на общее количество используемого бутилкаучука) агентов, контролирующих антиагломерацию и вулканизацию, обрабатывают галогенирующим средством в газовой фазе или в присутствии органического растворителя до тех пор, пока содержание галогенов в бутилкаучуке составит 0,5-2,5 вес.% и содержание непрогалогенированных двойных связей составит больше 0,7 мол.%. 2. A method for producing halogenated butyl rubbers according to claim 1, characterized in that butyl rubbers containing 1.0 to 2.2 wt.% (Calculated on the total amount of butyl rubber used) of antiagglomeration and vulcanization control agents are treated with a halogenated agent in the gas phase or in the presence of an organic solvent until the halogen content of butyl rubber is 0.5-2.5 wt.% and the content of non-halogenated double bonds is greater than 0.7 mol.%.
