Infrared Monitoring of the Modification of Styrene Acrylonitrile Copolymers with Oxazoline and Its Interfacial Reaction with Acid-Containing Polymers

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(ethy...

Description
Summary: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.
