Synthesis of New Hyperbranched Phosphorus-Containing Polyesters Starting from Boltorn H20

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, r...
