| סיכום: | Заглавие с титульного экрана Protolytic properties of fine-fiber plastics (FFP) based on polypropylene (PP), polyethyleneterephthalate (PET) and polycarbonate (PC) were investigated. Acidic (carboxylic, hydroxyl) and basic Lewiscenters (esters, carbonates, epoxies) were discovered on a surface of FFP using by IR spectroscopy. The numberof active groups of various nature and their pKa values were estimated by potentiometric titration of FFP in aqueous and non-aqueous media. The fibers tested possess low capacity for both acidic and basic centers on it. |
