Abstract

This invention relates to new high molecular weight arylene sulphide polymers which optionally additionally display improved resistance to UV radiation and are prepared by melting arylene sulphide polymers, preferably PPS, with polynitro compounds or with mononitro compounds containing at least one other substituent capable of reacting with the arylene sulphide polymer.
