The synthesis and characterization of linear telechelic polyisobutylenes having propargyl ether, propargyl ester and propiolic ester end groups are described. The syntheses were accomplished by reacting a, ?-di (hydroxy)-polyisobutylene with propargyl bromide or phthalic anhydride followed by propargylic alcohol or monopropargylic ester of phthalic acid chloride, or propiolic acid in the presence of different catalysts at room temperature (see Scheme 2). According to IR and 1H-NMR analyses quantitative conversions were obtained. |
