Abstract
"Process for modifying an aryl-vinyl (co) polymer, characterized in that the resin is first activated by mixing it with a small proportion of an alkali metal, at a temperature at which the resin and the metal are sufficiently soft, to be able to effect a homogenous dispersion of the metal in the resin, the mixture being continued until there is no more free metal in the dispersion and then it is mixed with the modifying substance (s) to be fixed on the activated resin.
