  • Thermally regenerable amphoteric ion exchangers prepared by sequential treatment of polymeric beads with two reagents of opposing acid base character
    Patent number: 4115297
    Abstract: A method of manufacturing amphoteric resins. Polymeric beads are treated sequentially with two reagents of opposite acid/base character. The resins are useful in the desalination of water.
    Type: Grant
    Filed: April 12, 1976
    Date of Patent: September 19, 1978
    Assignees: ICI Australia Limited, Commonwealth Scientific and Industrial Research Organization
    Inventors: Brian Alfred Bolto, Kurt Hermann Eppinger
  • Preparation of polymer composites
    Patent number: 4028255
    Abstract: A method for the preparation of composite particles having a specified range of particle size and comprising a finely divided, magnetic, particulate material embedded in a matrix of a linear polymeric material, which method comprises the steps of:A. forming discrete liquid droplets consisting of or containing the polymer, together with the particulate material;B. causing or allowing the droplets to form into solid particles;C. separating from the thus-formed particles those of the desired size range;D. re-converting the remaining particles to liquid form; andE. returning the re-liquified particles to step (a).
    Type: Grant
    Filed: October 6, 1975
    Date of Patent: June 7, 1977

    Inventors: Brian Alfred Bolto, Robert James Eldridge
  • Production of amphoteric resins in a reaction medium comprising formic acid
    Patent number: 3941724
    Abstract: In the known process of manufacturing an amphoteric polymeric composition which process comprises firstly polymerising a mixture comprising a monomer containing a basic group and a monomer containing an acidic group, the improvement of carrying out the process in the presence of a solvent system comprising formic acid.
