    Samenvatting

    Terminated polystyrene was esterified with 2,2,2-trifluoroethanol using a carbodiimide-mediated room temp. reaction, and hydroxyl-terminated polystyrene was fluoro-derivatized with trifluoroacetic anhydride. The so-formed fluorine-contg. esters were then quant. detd. with 19F NMR, using a,a,a-trifluorotoluene as secondary std. This provides a technique for the reliable detn. of carboxylic acid and hydroxyl groups in small samples of polymers. [on SciFinder (R)]
