COMPOSITION FILLED WITH ACTINOID POWDER AND AROMATIC POLYMER AND/OR POLYMETHYL METHACRYLATE Russian patent published in 2017 - IPC C08K3/22 C08K5/01 C08K5/09 C08L25/06 C08L33/12 C08L91/06 C08L23/12 

FIELD: chemistry.

SUBSTANCE: composition contains an organic matrix and an actinide powder or a mixture of actinide powders. Thus it comprises at least a plasticiser comprising an alkane, which is the longest radical chain comprises at least twenty carbon atoms, and the volume fraction of the plasticiser is from 20 to 70% of the total volume of only organic compounds, the binder comprising at least one aromatic polymer and/or methacrylate present in volume fraction from 20 to 50% of the total amount of organic compounds, and a dispersing agent comprising a carboxylic acid or its salt, a volume of which is less than 10% of the total organic compounds. In this case, said actinide powder or said mixture of actinide powders is 40 to 65 vol % of the volume of the filled matrix.

EFFECT: preparation of compositions filled with an actinide powder that are capable of withstanding radiolysis phenomena and are compatible with the properties necessary for passing the process for forming actinide powders by the MPI method.
