  • Process for deploymerizing polysulfides and the preparation of bis-mercapto-diethers
    Patent number: 9193679
    Abstract: The invention related to a process for the preparation of a bismercaptodiether by reacting a polysulfide with a monothiol in the presence of a base and to a process for the depolymerization of a polysulfide by reacting said polysulfide with a monothiol in the presence of a base. These processes enable the preparation of bismercaptodiethers without inorganic salt formation.
    Type: Grant
    Filed: March 11, 2015
    Date of Patent: November 24, 2015
    Assignee: AKZO NOBEL CHEMICALS INTERNATIONAL B.V.
