摘要： Mixtures of high molecular weight polyisobutylene and thermoplastic polymers are prepared in an extruder by a process in which meterable, high molecular weight polyisobutylene is first metered into the extruder and homogenized in at least one kneading stage, heated and subjected to controlled molecular weight degradation and the thermoplastic polymer is then introduced into the polyisobutylene melt by means of a side feed and is subsequently homogenized together with said melt. The novel process is particularly suitable for the preparation of mixtures of high molecualr weight polyisobutylene and polyethylene.

摘要： There is needed a process and an apparatus for the pyrolytic decomposition of halogen and/or phosphorus containing organic materials, particularly those which are radioactive, in which no corrosive secondary products, minimal amounts of waste gas, small amounts of dust and conditionable active solid waste form. This is accomplished by mixing the materials in an over stoichiometric ratio with basis compounds and introducing them from above in the form of a suspension into a fixed bed reactor which is charged with mechanically agitated substantially spherical ceramic structures.

摘要： For the operation of material-test-reactors, recently there have been considered fuels having lower degrees of enrichment in U-235. For this purpose, there is needed U.sub.3 O.sub.8 powder having a crystal size of 40 to 90 .mu.m, which is producible economically and in whose production there is developed as little secondary waste as possible and a pore-free product. For this purpose, uranium compounds of the stage of oxidation +4 to +6 are calcined in an oxygen containing atmosphere whereby the calcining is carried out above 1250.degree. C. in an atmosphere containing more than 30 volume % oxygen.
