Ester hydrolysis and depolymerization of polyester and polycarbonate polymers |
| 摘要 |
Ester bonds are hydrolyzed, such as in the conversion of polyesters to their monomeric components, by being contacted with a mixture of (a) an alcohol, such as methanol, or glycol, (b) a polar aprotic solvent such as N-methyl-pyrrolidone or dimethyl sulfoxide and (c) an alkoxide or hydroxide such as sodium hydroxide.
