| Abstract: | The kinetics of the modification of styrene acrylonitrile (SAN) with aminoethanol to oxazoline-containing copolymers has been monitored with FTIR spectroscopy. Further, the interfacial reaction in bilayer samples of the oxazoline groups of these copolymers and the carboxylic acid groups of poly(ethylene-co-methacrylic acid) (PE-co-MA) copolymers has been studied by FTIR at different temperatures. The interfacial formation of ester-amides has been measured quantitatively by FTIR difference spectroscopy. |
