Process for the manufacture of cross-linked poly(beta-alanine) in the form of micro-spheres |
| abstract |
Process for the preparation of crosslinked poly- beta -alanine in the form of microspheres. n<??>This process comprises the stages consisting:n a) in polymerising acrylamide in the tert-butanol/toluene solvent mixture in the presence of a polymerisation initiator and of an octadecene-maleic anhydride copolymer as dispersing agent,n b) in subjecting the poly- beta -alanine suspension obtained to crosslinking with the aid of a dialdehyde as crosslinking agent, andn c) in isolating the microspheres of crosslinked poly- beta -alanine. n<??>The microspheres obtained exhibit a narrow size scatter. |
