Abstract

Upon gentle treatment with SOCl₂, hyperbranched polyester Boltorn H₂0 afforded a mixture of terminal polychlorides. The latter react with an excess of triphenylphosphine in boiling toluene or with pyridine to give a mixture of polyesters with terminal triphenylphosphonium and pyridinium fragments, respectively.

Keywords:

Boltorn H20; hyperbranched polyesters; phosphonium chlorides
