Claim 7:
8. A method for processing a polylactic acid blend, the method comprising:
providing components comprising:
a polylactic acid containing carboxylic acid groups in an amount from 1.0 to at most 10.0 mg KOH/g,
an epoxide functional polymer comprising epoxide functional groups, wherein the epoxide functional polymer has a number average molecular weight of 1000 to 10.000 g/mol, and
a grafted polylactic acid, wherein the polylactic acid is grafted with an acid-functional ethylenically unsaturated polymerizable monomer and/or an acid anhydride-functional ethylenically unsaturated polymerizable monomer and has a total amount of carboxylic acid groups and carboxylic acid anhydride groups between 10.0 and 60.0 mg KOH/g;

mixing the components; and
melt processing the mixture.
