    Abstract: A medical prosthesis (10) includes a body having a silicone skin (14) and a silicone foam body core (16). The skin (14) and foam core (16) are both resilient. The core (16) includes a plurality of voids (18) and a plurality of discontinuities (28). Some of the discontinuities (28) communicate with more than one void (18).

    Abstract: Nanoporous materials are fabricated from polymers having backbones with reactive groups used in crosslinking. In one aspect of preferred methods and compositions, the reactive groups in the backbone comprise a diene and a dienophile. The diene may advantageously comprise a tetracyclone, and the dienophile may advantageously comprise an ethynyl. In another aspect of preferred methods and compositions, the reactive groups in the backbone are included in a conjugated system. Especially preferred polymeric strands comprise a poly(arylene ether) synthesized from a difluoroaromatic portion and an aromatic bisphenolic portion. It is still more preferred that the difluoroaromatic portions of the poly(arylene ether) are modified in such a way that some difluoroaromatic portions carry a themolabile portion. In still other aspects crosslinking may advantageously occur without reliance on a exogenous crosslinker.
