Over　the　past　16　years,　hyperbranched　polyesters　(HBPEs)　based　on　dimethylolpropionic　acid　have　received　much　attention　due　to　their　unique　structural　characters,　their　excellent　physical　and　chemical　properties　as　well　as　their　potential　applications　in　coatings,　additives,　drug　delivery,　composites,　membrane　science　and　supermolecular　chemistry.　HBPEs　have　recently　become　one　of　the　types　of　commercialized　hyperbranched　polymers,　and　their　modifications　and　applications　are　focuses　of　research.　This　paper　reviews　the　developments　in　the　modifications　and　applications　of　HBPEs.　(C)　2010　Society　of　Chemical　Industry
