Hyperbranched, aliphatic polyesters of theoretically calculated molar masses 1 200-44 300 (2-7 generations) were synthesized in the molten state from 2,2-bis(hydroxymethyl)propionic acid (bis-MPA) (repeating unit of AB(x)-type) and 2-ethyl-2-(hydroxymethyl)-1,3-propanediol (TMP) (core molecule) using acid catalysis. The synthetic procedure was a pseudo-one-step divergent reaction. The degree of branching was found to be near 80 %. A study has also been made with respect to the theological properties of the hyperbranched aliphatic polyesters. The polymers exhibit an almost newtonian behaviour in the molten state. They also exhibit a lower increase in viscosity with molecular weight than linear polymers. The surface functionality is shown to greatly affect the viscosity of the polymers.
