Solvent diffusion in poly(ether ether ketone)/poly(ether imide) blends

Solvent uptake in thin, amorphous samples of poly(ether ether ketone), poly(ether imide) and a 50/50 blend has been measured as a function of temperature. Diffusion coefficients, percentage weight increase and apparent activation energies have been calculated. The 50/50 blend shows anomalous diffusi...

Zusammenfassung:	Solvent uptake in thin, amorphous samples of poly(ether ether ketone), poly(ether imide) and a 50/50 blend has been measured as a function of temperature. Diffusion coefficients, percentage weight increase and apparent activation energies have been calculated. The 50/50 blend shows anomalous diffusion behaviour which may be attributed to specific interactions between the homopolymers and density changes on blending.
