Abstract: The invention relates to an incapacitant mixture comprising PAVA and a solvent, wherein the mixture capable of inducing temporary blindness in a human or animal. The mixture comprises less than 5 per cent PAVA and a solvent.

Abstract: A thermoplastic basic polymers in pourable form are mixed with similarly pourable carrier polymers dispersable or soluble in the basic polymers with a cross-linking agent to produce cross-linked polymer moldings. These mutually compatible components are heated under further mixing to a reaction temperature above the melting range of the basic polymer and processed. The reaction of free radicals leads to bonds between polymer chains and/or the degradation of polymer chains.Porous carrier polymers which contain at least one organic peroxide and/or coagent incorporated in the fine pore structure as a fluid silane-free cross-linking agent are mixed in the basic polymer. Peroxide-containing carrier polymers are heated, coagent-containing carrier polymers are irradiated.The moldings are used for example for cable and sheath isolation, pipes for hot water lines and highly stressed injection moldings.

Abstract: The pourable porous carrier material is produced from at least one thermoplastic basic polymer with additives incorporated in the porous structure.First suitable foaming agents are added to the basic polymer, the mass is melted, mixed before and/or after melting. The mixture is then preferably extruded and cooled to form a pourable porous carrier material.At least one additive is added to the porous carrier material and mixed with this at a temperature (T.sub.M) below the melting point of the basic polymer but above the melting point of the additive.The porous carrier material has preferably ellipsoid pores which are brought into their longitudinal form during extrusion.
