Abstract: Aseries of hyperbranched polyesters with controlled inherent viscosities have been prepared by polycondensation of 3,5-bis(trimethylsiloxy) benzoyl chloride with sililated p-methyl aniline under various molar ratios. After reacted with acid chlorides in o-dichlorobenzene, the functionalization of these polyesters was readily accomplished. The end groups of the crude polymers were effectively transferred into vinylic and ethynylic groups in high yields(>85%) as calculated by 1H NMRspectra without any change in their inherent viscosities.
