Résumé / Abstract

Mechanical properties of binary melt mixed blends of various polyamides (Nylon 11; 6,6; 6,10; 6,12) with a block copolyetherester (PEE) were investigated. All the blends prepared had very good mechanical properties and in some cases even better than those of the respective pure polyamides. Two of the systems (Nylon I I/PEE and Nylon 6,12/PEE) were selected to be studied further in terms of morphology, viscoelastic and thermal properties. These blends showed two distinct but mutual shifting T_g's and low extracted amount of PEE during extraction experiments, supporting the view that a very good interfacial grafting had been achieved in these two-phase systems. This assumption was further evaluated on the cryofractured and selectively etched blends where the existence of the grafted PEE was justified by Fourier transform infrared as well as by micro-Raman spectroscopy.
