  • Selective modification of pendent functionalities of polymers
    Patent number: 6916868
    Abstract: A process for selectively modifying pendent functionalities of a polymer containing the pendent functionalities and hydrolytically unstable backbone functionalities is provided. The process includes: (a) providing the polymer in a solvent system (preferably an ether-containing solvent system) adapted to maintain the polymer in a dissolved or partially dissolved state, wherein the pendent functionalities of the polymer are more accessible than the hydrolytically unstable backbone functionalities; and (b) adding at least one additive to the solvent system to selectively modify at least one of the pendent functionalities. The process is especially well suited for specifically acid hydrolyzing pendent esters of PDTE.
    Type: Grant
