Abstract
The study attempted to establish the optimum reaction conditions for o btaining soluble chloromethylated polystyrene with a transformation de gree higher than 50%. A paraformaldehyde and chlorotrimethylsilane mix ture as chloromethylation agent and SnCl4 as catalyst were used. The t ransformation degree followed by the chlorine content depends on the f ollowing parameters: temperature, time, and [SnCl4]/[PS] and [Me(3)ClS i]/[PS] molar ratios.
