  • Method for making polyarylaliphaticetherketone polymers and copolymers thereof
    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.
