PROCESS FOR THE REMOVAL OF RESIDUAL MONOMERS FROM ABS POLYMERS

摘要

Process for the removal of residual monomers from ABS polymers prepared by emulsion polymerization, wherein from 0.1 to 10 X by weight, based on the solids content in the latex, Or an electrolyte such as an acid or a salt are added to a latex containing an ABS polymer, and the mixture is at the same time heat d to a temperature Or from 55 to 120 /A while the residual mnomer and part of the water are removed by diatillation.
