ABSTRACT:
Heat-stable poly(ethynylene phenylene ethynylene polysiloxene(silylene)) polymers preferably of determined molecular mass, optionally bearing at the end of the chain groups derived from a chain-limiting agent. Processes for preparing these polymers, cured products obtained by heat-treating these polymers, and composite matrices comprising these polymers.
