  • Process of preparing substantially solid waste containing radioactive or toxic substances for safe, non-pollutive handling, transportation and permanent storage
    Patent number: 4131563
    Abstract: A process of preparing substantially solid wastes containing radioactive or toxic substances for safe, non-pollutive handling, transportation and permanent storage, wherein the wastes are mixed with polymerizable mixtures consisting essentially of monovinyl and polyvinyl compounds and polymerization catalysts, and are converted by polymerization into solid blocks.
    Type: Grant
    Filed: August 25, 1976
    Date of Patent: December 26, 1978
    Assignee: Steag Kernenergie G.m.b.H.
    Inventors: Werner Bahr, Stefan Drobnik, Werner Hild, Reinhard Kroebel, Alfred Meyer, Gunter Naumann
  • Process of preparing substantially organic waste liquids containing radioactive or toxic substances for safe, non-pollutive handling, transportation and permanent storage
    Patent number: 4009116
    Abstract: A process of preparing substantially organic waste liquids containing radioactive or toxic substances for safe, non-pollutive handling, transportation and permanent storage, wherein the liquids are mixed with polymerizable mixtures consisting essentially of one or more monomeric monovinyl compounds and one or more polyvinyl compounds and polymerization catalysts, and the resulting mixtures are converted into solid blocks by polymerization at temperatures in the range of from 15.degree. to 150.degree. C.
    Type: Grant
    Filed: December 20, 1974
    Date of Patent: February 22, 1977
    Assignee: Bayer Aktiengesellschaft
    Inventors: Werner Bahr, Stefan Drobnik, Werner Hild, Reinhard Kroebel, Alfred Meyer, Gunter Naumann
  • Process for the production of anion exchangers - amidoalkylation of crosslinked water insoluble aromatic-group containing polymers using esters of cyclic N-hydroxyalkylimides
    Patent number: 3989650
    Abstract: This invention relates to a new process for the production of crosslinked, water-insoluble synthetic resins with anion exchanger properties wherein the crosslinked, water-insoluble organic polymers containing aromatic nuclei are reacted, in the presence of swelling agents for the polymer and in the presence of acid catalysts, with esters of N-hydroxyalkylamides or N-hydroxyalkylimides, and the acylamido alkylated reaction product is subsequently hydrolysed in known manner. The invention furthermore concerns new crosslinked water-insoluble synthetic resins with anion exchanger properties containing at least two aminoalkyl groups per aromatic nucleus.
