Abstract
This method is used in the production of butadiene-styrol and butadiene- -methylethyrol rubber and latex, which enhances the aggregate resistance of latex and reduces the formation of coagulate.Description : from 50 to 80% of the total quantity of the disperser is introduced in the polymerisation system before the start of polymerisation, while between 20 and 50% is introduced in the latex along with the stopper before degassing, or at once, or at even parts before each phase of degassing.
