The effects of reprocessing by injection molding on the structure and properties of poly(ether imide) (PEI) were studied. The chemical structure of PEI does not change after reprocessing. However, the weight-average molecular weight decreases after the first and the second injection cycles, after wh
## Abstract Blends of PEI with an amorphous copolyester (PCTG) were obtained by melt‐mixing followed by injection molding. The processability of PEI increased several times upon addition of just 10% PCTG, thus expanding the applications of PEI. All the blends showed a single __T__~g~ and most of th
