Abstract:
The invention relates to a PET regranulate which, after modification of a granulated PET recyclate, has an intrinsic viscosity of at least 0.95 dl/g measured according to ASTM D 4603, preferably greater than 1.0 dl/g and particularly preferably between 1.1 dl/g and 1.7 dl/g and is suitable for the production of extrusion blow-molded containers.
