INTERMOLECULAR INTERACTIONS AND MISCIBILITY IN BLENDS OF POLYAMIDES CONTAINING SULFONIC GROUPS

Intermolecular interactions in blends of poly-m-phenylene isophthalami de with aromatic polyamide containing sulfonic groups -poly-p-(2,2'-di sulfonate sodium salt)diphenylene isophthalamide was studied in the wo rk. It was shown not additive changes of breaking strength, the carbon dioxide permeability of blends and viscosity of solution of these ble nds in dependence on composition. The formation of bond between sulfon ic and amide groups of polymers was shown by means of IR-spectroscopy studies. The conclusion was done about effect of conditions of formati on and content of the blends of polymers on the morphology using DSC d ata and IR-spectroscopy studies.
