| Abstract: | The first and second generation of dendritic polyesters have been prepared by divergent synthetic ways using trimethylopropame(TMP) as core and o-phthalic anhydride(OPA), glycidol as branched units. The effects of reaction temperature, ratio of reactants and the ways of adding reactants on reaction conversion, molecular weight and molecular weight distribution of the oligomer were studied. The dendrimers were characterized by GPC, FT-IR,~(1)HNMR. |
