ABSTRACT:
Organic pigments for thermoplastic polymers are prepared by the anionic initiated slurry polymerization of styrene and 0.5-15 weight percent divinylbenzene based upon styrene in the presence of a block polymer dispersant, using, as the anionic initiator, an alkali metal-bearing compound at 20.degree. C. to 120.degree. C. to produce a finely divided solid cross-linked polymer and terminating the polymerization by reaction of the polymer particles with an organic dye, an organic dye precursor, or with a reactive coupling agent followed by reaction with an organic dye.
