Abstract
The invention relates to a method for the purification of a resorbable polymer from residual monomers comprising the addition of a solution of said polymer in a solvent and the addition of a precipitation agent into a mixing chamber to precipitate the polymer, characterized in that the concentration of the polymer in the solution is log Ccrit±0.3 logarithmic units, wherein Ccrit is the critical concentration.
