<p>The invention relates to a process for the preparation of a polymer from heterocyclic monomer units. The process according to the invention is characterized in that polymerization takes place in the presence of a sulphur-containing reagent. It has been found that the process according to the invention can be used to prepare polymers that can readily be processed, either in solution or in the melt. It has further been found that the reaction time of the reaction that takes place is short, while also the efficiency of the reaction is good. In the process according to the invention use can be made of monomer units that are thermostable. Such monomer units are easy to synthesize and easy to keep.</p> |
