Abstract

There are disclosed composite particles formed of polyimide structural units of the general formula (see formula I) wherein R represents 2,4- and/or 2,6-toluene or a biphenylmethelyene group and of filler cores. They may be compressed to shaped articles, Glass, mica, graphite or PTFE may be used as fillers.
