Procedure

A dispersion of a core/shell polymer which had a core of n-butyl acrylate and dihydrodicyclopentadienyl acrylate (weight ratio 98:2) and a shell of n-butyl acrylate and methacrylic acid (weight ratio 98:1.5) and a core/shell weight ratio of 60:40 and which had been obtained by emulsion polymerization in a conventinal manner was mixed with red phosphorus and the sodium salt of a C12 -C18 -alkanesulfonic acid in a stirred kettle at room temperature. The mixing time was 30 minutes.
