  • Continuous process for the preparation of acrylonitrile polymers and copolymers
    Patent number: 3987018
    Abstract: A continuous process for polymerizing acrylonitrile monomer or copolymerizing a mixture of acrylonitrile monomer and a further ethylenically unsaturated monomer copolymerizable therewith in an aqueous medium and in the presence of a catalytic redox system through a primary and a secondary polymerization step. The primary step is carried out in a plurality of independent distinct reaction zones connected in parallel and operated under similar conditions, in which the conversion of the monomer or mixture of monomers is maintained at a value not exceeding 70%. The secondary step is carried out in a single reaction zone connected in series with each of the primary zones. The conversion of the monomer or mixture of monomers in the secondary zone is maintained at a value not exceeding 80% with respect to the overall feed of monomer or mixture of monomers to the primary zones.

  • Separation and recovery of products obtained in catalytic processes of preparing acrylonitrile polymers or copolymers
    Patent number: 3965079
    Abstract: Sulphur dioxide and unreacted monomer or mixture of monomers are separated and recovered from the polymer or copolymer slurry obtained by polymerizing acrylonitrile monomer or copolymerizing acrylonitrile monomer and a further ethylenically unsaturated monomer copolymerizable therewith in the presence of a catalytic system comprising sulphur dioxide or a sulphite, by a process comprising the steps of separately removing the sulphur dioxide and the monomer or mixture of monomers from the slurry in two distinct volatilization zones connected in series under decreasing subatmospheric pressures, scrubbing with water the sulphur dioxide vapors removed in the first zone and vapors of unreacted monomer or monomers removed in the second zone, and recycling the two resulting aqueous solutions to the polymerization or copolymerization medium.

  • Catalytic process for the preparation of polyacrylonitrile and acrylonitrile copolymers
    Patent number: 3959240
    Abstract: A process for polymerizing acrylonitrile monomer or copolymerizing a mixture of acrylonitrile monomer and further ethylenically unsaturated monomers copolymerizable therewith, which comprises contacting the monomer or mixture of monomers in an aqueous medium at a temperature not exceeding 55.degree.C with a catalytic system comprising a watersoluble persulphate, a hydroxylamine mono- or disulfonate and a water-soluble salt of a variable valence metal, such as a ferrous salt.
