Abstract
The invention relates to a method in which a starting material for injection-molding, having a viscosity of between 0.50 and 0.7 dL/g, is produced with the aid of a chain breaker from a recycled post-consumer PET having a viscosity of between 0.72 and 0.86 dL/g according to ASTM D4603 and a copolymer fraction of at most approximately 3%. In the method, the comminuted and dried PET material is melted and decontaminated to such a degree that it is suitable for applications in the food sector and the consumer goods sector. A chain breaker is added to the rPET material in the melt of the recycling extruder and/or preferably the melt of the injection unit in order to lower the viscosity and to enrich the PET with copolymers.
