| Abstract: | This paper describes a study of the crystallization behaviour of blends consisting of the polymers poly (ether ether ketone) (PEEK) and poly (ether imide) (PEI) using Fourier transform Raman spectroscopy. The annealing process of PEEK was followed for the virgin polymer and also when it was blended with PEI. The data presented show that the crystallization process of PEEK is inhibited by the presence of the PEI, but the extent of the crystallinity is increased. There is also evidence that the presence of the PEI induces premelting of the PEEK. |
