  • POLYMERISATION PROCESS AND POLYMER PRODUCT
    Publication number: 20170333942
    Abstract: A method of polymerising monomer to form polymer at the surface of particulate material, said method comprising: providing a dispersion of said particulate material in a continuous liquid phase, said dispersion comprising a RAFT agent as a stabiliser for said particulate material, and said continuous liquid phase comprising one or more ethylenically unsaturated monomers; and polymerising said one or more ethylenically unsaturated monomers under the control of said RAFT agent to thereby form polymer at the surface of said particulate material.
    Type: Application
    Filed: July 14, 2017
    Publication date: November 23, 2017
    Inventors: Brian Stanley HAWKETT, Christopher Henry SUCH, Duc Ngoc NGUYEN, Jason Michael FARRUGIA, Olga Maree MACKINNON

  • Aqueous polymer dispersion
    Patent number: 7858695
    Abstract: The invention provides a process for preparing an aqueous dispersion of water insoluble heteropolymeric particles comprising polymerising in an aqueous reaction medium ethylenically unsaturated monomers, said ethylenically unsaturated monomers comprising ionisable ethylenically unsaturated monomers and non-ionisable hydrophilic ethylenically unsaturated monomers, to form said heteropolymeric particles dispersed in said aqueous reaction medium, wherein the monomers in said reaction medium at any point in time comprise less than 5 weight % of ionisable ethylenically unsaturated monomer, wherein for at least a part of the polymerisation the monomers in said reaction medium have a composition which is maintained with an ionisable ethylenically unsaturated monomer content of from 0.
    Type: Grant
