Process for preparing hyperbranched polyesters at atmospheric pressure by reacting polyols with polycarboxylic acid in the presence of a heterogeneous, reusable, acid, crystalline, micro-mesoporous double-metal cyanide catalyst ZnM(CN)(ROH).xZnCl.yHO at moderate temperatures for a short period of reaction time. Examples of a polyol include glycerol, sorbitol, mannitol, glucose and sucrose. Examples of a polycarboxylic acid include succinic acid and adipic acid. The hyper-branched polyester produced has a high degree of branching (56-90%), a low viscosity (inherent viscosity 0.02-0.1 dL/g), and a controlled gelation.
