Antireflective coatings

The present invention relates to polymeric networks that can be made electrically conductive in bulk or which have a surface which is electrically conductive, and which networks exhibit resistivities in the ohm to kilo-ohm range. One aspect of the present, thermosetting invention, then, comprises an electrically conductive polymeric network comprising a cured polymeric network which contains an oxidized additive comprising one or more of an oxidizable aniline, thiophene, or pyrrole additive, which additive was oxidized with an oxidizing agent in situ in the cured polymeric network.

Electrically-conductive and ionically-conductive polymeric networks and

The present invention is directed to a non-emissive, bimodal cured polymeric network which has an onset degradation temperature that is about 100.degree. C. above the onset degradation temperature of a base polymer. The novel cured polymeric network comprises the cured reaction product of the following ingredients: (a) combination of one or more liquid carrier monomers or prepolymers which combination is reactive to form a base polymer by exposure to ultraviolet (UV) radiation in the presence of a UV photosensitizer at a temperature, T.sub.uv ; and (b) between about 10 and 100 wt-% based on ingredient (a) of a combination of one or more monomers or prepolymers which combination is reactive to form a cured high temperature stable polymer by heating at a temperature, T.sub..DELTA.. Ingredient (b) is soluble or dispersible in ingredient (a) at a temperature, T.sub.s, wherein T.sub.s is equal to or lower than T.sub.uv, and T.sub.uv is at least about 50.degree. C. lower than T.sub..DELTA..
