Poisoned modified polymer of poly(ethynylene phenylene ethynylene silylene) type that may be obtained by selective addition of a compound containing only one reactive function to the acetylenic bonds of a poly(ethynylene phenylene ethynylene silylene) polymer. Compositions containing these modified polymers. Process for preparing these modified polymers. Novel self-poisoned polymers of poly(ethynylene phenylene ethynylene silylene) type. Cured products that may be obtained by heat treatment of the said modified or self-poisoned polymers. The polymers and cured products have improved mechanical properties while maintaining excellent thermal properties.
