AROMATIC ALPHA,OMEGA-DIYNE OLIGOAMIDES - POLYMERIZABILITY, THERMOSTABILITY AND ADHESIVITY

alpha,omega-diynes oligoamides are synthesized as thermostable network precursors. Through the analysis of the crosslinking reactions and of the thermal stability, three models are chosen with the aim of studyi ng their adhesivity (evaluation of free surface energies and interacti ons with standard liquids). The molecular structures are then correlat ed with adhesiveness. In the last part of the paper, the results of ad herence lap shear tests (aluminium probes) evidence a fair stability o f the adhesive properties up to 200 degrees C. (C) 1997 Elsevier Scien ce Ltd.
