ABSTRACT:
The invention relates to the stabilization of monobromostyrene of dibromostyrene and of mixtures of these. The stabilization is effected by means of hydroxy-benzene derivatives, where the benzene ring contains at least two substituents, one of these being a hydroxy group. The process is advantageously carried out by heating the styrene material with an excess of the inhibitor, distilling the monomer and adding an additional quantity of the inhibitor. The distilled monomer is preferably dried prior to the addition of the further quantity of inhibitor.
