Abstract: The present invention has an object of providing a light emitting device including an OLED formed on a plastic substrate, which can prevent the degradation due to penetration of moisture or oxygen. On a plastic substrate, a plurality of films for preventing oxygen or moisture from penetrating into an organic light emitting layer in the OLED (hereinafter, referred to as barrier films) and a film having a smaller stress than that of the barrier films (hereinafter, referred to as a stress relaxing film), the film being interposed between the barrier films, are provided. Owing to a laminate structure of a plurality of barrier films, even if a crack occurs in one of the barrier films, the other barrier film(s) can effectively prevent moisture or oxygen from penetrating into the organic light emitting layer. Moreover, the stress relaxing film, which has a smaller stress than that of the barrier films, is interposed between the barrier films, thereby making it possible to reduce a stress of the entire sealing film. As a result, a crack due to stress hardly occurs.

Abstract: The invention relates to the military filed of explosive munitions. A subject-matter of the invention is a semi-continuous process for producing a composite explosive charge comprising a charged solid polyurethane matrix, the charge of which is pulverulent and comprises at least one nitro-organic explosive, by introduction into a mould of a pasty explosive composition and then thermal crosslinking of this composition. The composition is obtained by mixing constituents essentially comprising a polyol prepolymer, a plasticizer, a polyisocyanate monomer and a pulverulent solid charge comprising at least one nitro-organic explosive. More specifically, 2 components: a pasty component A comprising all the polyol prepolymer and all the pulverulent solid charge, a liquid component B comprising all the polyisocyanate monomer, the plasticizer being distributed without distinction between the 2 components A and B, are first of all prepared from the combined constituents. The component A and the component B are subsequently mixed under continuous conditions such that the component A/component B ratio by mass is constant and between 95/5 and 99.5/0.5. This simple and economic process makes it possible to dispense, without disadvantage, with the pot life/curing time of the composition compromise.
