PROCESS FOR OBTAINING POLYPARAPHENYLENE VINYLENE POLYMERS OR POLYPARATHIENYLENE VINYLENE POLYMERS

摘要

The invention relates to an original process for obtaining polymers of the polyparaphenylene vinylene type or of the polyparathienylene vinylene type using a polyelectronium precursor based on sulfoniums. An acid treatment of such a precursor makes it possible to obtain the desired polymers directly. BR/ These polymers of high molecular masses are particularly interesting in the field of plastics. / P
