This paper describes a study of the crystallisation behaviour of a blend consisting of the polymers poly(ether ether ketone) (PEEK) and poly(ether sulphone) (PES) using Fourier transform Raman spectroscopy. The annealing process of PEEK is followed for the unblended polymer and also when it is blended with PES. The data presented shows that the rate of crystallisation of PEEK is slower in the presence of PES when compared with the crystallisation process of unblended PEEK. The data supports the theory that the glass transition temperature of PEEK is elevated in the presence of PES.
