This manuscript represents an experimental investigation about the thermal properties of polymeric Polyetherimide (PEI) / Polyethyleneterephthalate-glycol (PEG) blends, with the aim to improve the processability of pristine PEI without an excessive decrease of its properties, thus obtaining a suitable material to feed machines for rapid prototyping, in particular for the fusion deposition modelling (FDM) production technique. Mixtures with 5 and 10% of PETG were obtained applying the melt blending technique using a batch mixer. The materials obtained from the latter were subjected to a thermomechanical process in order to obtain pellets, used as feed for an injection-moulding machine, thus suitable to be employed for the various characterizations. The blends were characterized through thermal (TGA and DSC) and morphological (SEM) analysis.

This manuscript represents an experimental investigation about the thermal properties of polymeric Polyetherimide (PEI) / Polyethyleneterephthalate-glycol (PEG) blends, with the aim to improve the processability of pristine PEI without an excessive decrease of its properties, thus obtaining a suitable material to feed machines for rapid prototyping, in particular for the fusion deposition modelling (FDM) production technique. Mixtures with 5 and 10% of PETG were obtained applying the melt blending technique using a batch mixer. The materials obtained from the latter were subjected to a thermomechanical process in order to obtain pellets, used as feed for an injection-moulding machine, thus suitable to be employed for the various characterizations.
