METHOD FOR THE PRODUCTION OF SULPHOROUS POLYMERS

摘要

The present invention relates to a process for preparing sulfur-containing polymers from at least one sulfide and at least one aromatic dihalo compound in a solvent, which comprises a) reacting the sulfide with a stoichiometric excess of aromatic dihalo compound, b) largely removing the excess aromatic dihalo compound and c) further polymerizing the mixture.
