Title: Radiation reactive precursors of highly heat-resistant polymers, and their use
Inventor: AHNE HELLMUT DR
IPC: C08G73/18
Filed: 1981-06-01
Granted: 1985-02-07
Abstract: The invention relates to oligomeric and/or polymeric radiation-reactive precursor stages of polymers on the basis of heterocycles and has the objective to make available radiation-reactive precursor stages of this kind in which the problems arising due to the need of using organic solvents are eliminated. For this purpose, the invention provides addition products of cyclic carboxylic-acid anhydrides with hydroxyl group-containing compounds, where the hydroxyl group-containing compounds represent addition products of olefinically unsaturated monoepoxides on carboxyl group-containing prepolymers of polyimides, polyisoindoloquinazoline diones, polyoxazine diones and polyquinazoline diones or on amino group-containing prepolymers of polyimidazoles and polyimidazopyrrolones or on hydroxyl group-containing prepolymers of polyoxazoles. The radiation-reactive precursor stages according to the invention are suited, for example, for the manufacture of highly heat-resistant relief structues.

Title: A process for the preparation of aluminium-containing high-energy explosive compositions
Inventor: ULSTEEN KARE
IPC: C06B21/00
Filed: 1981-02-26
Granted: 1985-07-04
Abstract: A castable high-energy explosive composition comprising trinitrotoluene (TNT) and crystalline explosives of the RDX or HMX type as well as aluminium powder, and, optionally, flegmatising agents and stabilisers consisting of wax, lecithin and nitrocellulose (NC), is prepared by dispersing crystals of RDX or HMX in water with wax, under heavy stirring and at a temperature above the melting point of the wax, then adding aluminium powder, treated in order to tolerate water, to the dispersion, and then, optionally, cooling in order to separate the explosive as granules. A further step comprises melting and dispersing TNT in hot water under heavy stirring, optionally under the addition of wetted NC and lecithin, then reducing the temperature to below 80°C, and separating the solidifying, dispersed explosive droplets in the form of granules.The final step comprises mixing the products from the former steps in specific ratios so as to provide the final explosive compositions known by the name "Hexotonal" or "Octonal", respectively. Alternatively, the mixtures of granules from the first two steps are melted together and cast on a drum, ribbon or plate, or the first two steps are combined in the same reactor before any part of the dispersed phases has solidified.

Each of the apertures (106) and (108) and plates (112) and (114) are operable to generate a microwave field pattern having a higher order than that of the container, said field pattern propagating into the container to heat the material. This is achieved in the arrangement illustrated by amplifying the 2nd order mode within the container which has been found to give improved heat distribution within the material being heated. Several other alternative arrangements are possible, some of which are illustrated in the specification.
