  • Process for polymerization using monoperoxyoxalic acid diesters
    Patent number: 4455412
    Abstract: The invention concerns a process for the polymerization of vinyl chloride monomer (VCM) using as initiator a diester of monoperoxyoxalic acid. The initiators are highly active and the process provides a method for the efficient polymerization of VCM at lower temperatures and/or for shorter reaction times than can be achieved with the current commercially available catalysts.

  • Process for removing unsaturation from ion exchange resins containing unquaternized amino groups by hydrogenation with imine
    Patent number: 4221872
    Abstract: A process of removing unsaturation from resins by reaction with diimine. Thermally regenerable ion exchange resins are prepared by the hydrogenation of unsaturated polymers containing unquaternized amino groups with diimine. Procedures for generating the reactive diimine intermediate from precursors such as hydrazine are described.

  • Process for making composite magnetic material
    Patent number: 4211664
    Abstract: A process for making dimensionally-stable composite materials comprising adsorbents and magnetic particles embedded in a porous matrix of organic polymeric materials. The magnetic particles enable the composites to be easily and rapidly removed from treated solutions after the adsorption stage is complete.
