SURFACE MODIFICATION OF ESTER-CONTAINING POLYMERS WITH ANIONIC DERIVATIVES OF AMINE-TERMINATED OLIGOMERS Academic Article uri icon

abstract

  • The use of metalated derivatives of ,-diaminopoly(alkene oxide) oligomers as reagents to modify the surface of ester-containing polymers like poly(methyl methacrylate) and poly(ethylene terephthalate) with concomitant introduction of amino groups onto the surface of these films is described. Metalation significantly activates these amino-containing oligomers since the nonmetalated oligomers do not react to an appreciable extent under these conditions (60 C, mixed ether-heptane solvent) with these ester-containing polymers. The modified surfaces have greatly enhanced hydrophilicity and contain predominantly ,- diaminopoly(alkene oxide) groups covalently bound through a terminal monoamido group based on ATR-IR and XPS spectroscopy. Cross-finking occurred but to only a limited extent. The unreacted amino groups of the ,-diaminopoly(alkene oxide) were chemically reactive and acted both as nucleophiles and bases in reactions with soluble reagents. 1992, American Chemical Society.
