摘要:

The study attempted to establish the optimum reaction conditions for obtaining soluble chloromethylated polystyrene with a transformation degree higher than 50%. A paraformaldehyde and chlorotrimethylsilane mixture as chloromethylation agent and SnCl4as catalyst were used. The transformation degree followed by the chlorine content depends on the following parameters: temperature, time, and [SnCl4]/[PS] and [Me3ClSi]/[PS] molar ratios.
