  • Degradable polycations derived from amino acid vinyl esters
    Patent number: 9688789
    Abstract: Described herein are the synthesis and polymerization of a series of N-Boc-protected amino acid vinyl ester (BAAVE) monomers. Homopolymers and heteropolymers containing the monomers are described, particularly heteropolymers with vinyl ester monomers such as vinyl acetate. Deprotection can be used to produce hydrophilic and hydrophobic polymers that are particular useful in biological applications such as cellular delivery of biological materials.
    Type: Grant
