    Abstract: A composition has a polymeric network that includes a porogen and a photoinitiator. The photoinitiator produces a reactive species upon irradiation, which reacts with the porogen in a degradation reaction that degrades at least some of the porogen. A method of forming a nanoporous polymer has one step in which a plurality of polymeric strands, a photoinitiator, and a porogen are provided. In a subsequent step, at least some of the polymeric strands are crosslinked to form a polymeric network that includes the porogen and the photoinitiator, and in a further step the photoinitiator in the polymeric network is irradiated to generate a reactive species that reacts with the porogen in a degradation reaction to degrade at least some of the porogen.

    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 thermolabile portion. In still other aspects crosslinking may advantageously occur without reliance on an exogenous crosslinker.

    Abstract: A printing material composed of an open-cell sponge rubber capable of including therein a colored ink, which does not necessitate a stamp pad for the stamping operation, is disclosed. This printing material is prepared by adding appropriate amounts of soluble starch and a fine powder of an easily water-soluble salt which does not decompose or gasify at a curing temperature to a mixture of a starting rubber, a curing agent and a filler, kneading and milling the mixture, introducing the mixture into a mold, heating the mixture to effect curing, removing said starch and salt by washing, and drying the resulting product.
