Purification methods comprising the use of membranes obtained from bio-based sulfone polymers |
| abstract |
The invention pertains to a purification method for a biological fluid comprising at least a filtration step through a membrane obtained from a sulfone polymer [polymer (PSI)] derived from bio-based feed-stocks. In particular the PSI polymer comprises more than 50% moles recurring units (RPSI) comprising sugar moieties selected from the group consisting of those of formulae (E′-1) to (E′-3):The invention further relates to polymer solutions and polymer membranes comprising at least one polymer (PSI) and that are free from pore-forming agents. |
