Abstract:
The invention relates to a method for the production of a homo- or copolymer of a poly- beta -hydroxyalkanoic acid (PHA) from biomass, characterized in that the biomass is extracted by 1-methyl-2-pyrrolidone (NMP), optionally using a water binding agent, from a viscous suspension which forms at a temperature >/= of 40 DEG C. PHA-containing solution is separated out and PHA is subsequently precipitated out.
