Alkylation of vinyl aromatic polymer

Effective organic fluid-insoluble organic fluid-swellable polymer particles are prepared from vinyl aromatic polymer particles. Alkyl halide alkylating agents are allowed to react with the vinyl aromatic polymer particles after they are swollen by an organic swelling medium. At least a portion of th...

Zusammenfassung:	Effective organic fluid-insoluble organic fluid-swellable polymer particles are prepared from vinyl aromatic polymer particles. Alkyl halide alkylating agents are allowed to react with the vinyl aromatic polymer particles after they are swollen by an organic swelling medium. At least a portion of the organic swelling medium may optionally be removed. The particles may optionally be swollen with at least one additional monomer, which may then be polymerized.
