Soluble aromatic hyperbranched polyesters with controlled viscosities have been preparedby melt polycondensation of sililated 5-acetoxyisophathalic acid with sililated p-tert-butyl benzoic acidin various molar ratios. By further reaction with thionyl chloride and propargyl alcohol successively,the endgroups of the crude polyester were transferred into ethynylic groups in 78. 2％ yield as calculat-ed by 1H NMR spectra.
