What is Some Solid-state Properties of Blends of Polyethylene Terephthalate and Polyamide-6,6 about?

## Abstract Polymer blends incorporating polyamide‐6,6 (PA) and polyethylene terephthalate (PET) and having the following PA wt,% concentrations were prepared: 0, 5, 10, 25, 30, 35, and 100. Samples were obtained by molding in a reciprocating‐screw injection‐molding machine. The samples were annealed to minimize frozen‐in stresses without increasing the crystallinity level in the material. Melting and heat‐of‐fnsion data, obtained with the differential scanning calorimeter, suggest an overall increased crystallinity in the blends, as indicated by a significant excess heat of fusion. Whereas the neat polymers exhibit ductile failure under both tensile and impact testing conditions, the blends show brittle behavior. Finally, the abrasion resistance of the blends is inferior to that observed for PET but higher than the resistance of PA.
