  • Patent number: 10800876
    Abstract: The present invention provides a method of preparing a polyaryletherketone copolymer (e.g. a random or block copolymer), said method comprising: polymerizing (i) a monomer system suitable for forming aryletherketone units and (ii) a comonomer in a reaction medium comprising: (a) a Lewis acid and (b) a controlling agent comprising an aromatic carboxylic acid, an aromatic sulphonic acid, or a derivative thereof; and polymers produced therefrom.
    Type: Grant
    Filed: May 21, 2015
    Date of Patent: October 13, 2020
    Assignee: Ketonex Limited
    Inventors: Ian David Henderson Towle, Kaylie Jane Smith, Pauline Julia Siddons
  • Patent number: 10450408
    Abstract: A process for producing a polymer includes polymerizing a monomer system containing a compound of formula: Ar—O—Ar—C(?O)—X—C(?O)—Ar—O—Ar in a reaction medium containing a Lewis acid. In the formula, X is an aliphatic moiety, and Ar is an aromatic moiety. The reaction medium further includes a dielectrophile. The dielectrophile is a compound of formula: L-(O?)C—Ar—C(?O)-L, in which L is a leaving group.
    Type: Grant
