Purification of p-dioxanone |
| abstract |
The present disclosure provides methods for purifying p-dioxanone. In embodiments, crude p-dioxanone may be contacted with at least one isocyanate-functionalized scavenger. The at least one isocyanate-functionalized scavenger may react with hydroxyl compounds present with the crude p-dioxanone to form reaction products, in embodiments polyurethanes and/or polyureas, which may then be removed. The p-dioxanone thus obtained is of greater purity than the starting crude p-dioxanone. |
