Process for the preparation of crosslinked poly β-alanine in the form of microspheres |
| abstract |
A process for preparing crosslinked poly beta -alanine in the form of microspheres comprises (a) polymerizing acrylamide in a tert. butanol/toluene solvent mixture in the presence of a polymerization initiator and an octadecene-maleic anhydride copolymer as a suspension agent; (b) submitting the resulting suspension of poly beta -alanine to a crosslinking reaction using a dialdehyde as the crosslinking agent; and (c) isolating the crosslinked poly beta -alanine microspheres. These microspheres exhibit a low size dispersity. |
