Abstract
Several poly(ethylene glycol) mixed carbonates and their preparation are closed. These carbonates are synthesized by conversion of polyethylene glycol first to the chloroformate then by reaction with the hydroxyl group of N-hydroxybenzotriazole or 2-hydroxypyrimidine or N-hydroxy-2-pyrrolidinone. These mixed carbonate analogs smoothly react with amino groups in aminoglycans and protein and amino containing surfaces to form stable, hydrolysis resistant carbamate linkages.
