✦ Synopsis

Abstraet--Oligoethers with hydroxyl end-groups were prepared in boiling toluene from bis(chloromethyl)methylphosphine oxide and glycols used as monosodium glycolates. From these oligoethers and diisocyanates (hexamethylenediisocyanate and 2,4-toluene-diisocyanate), phosphorus-containing polyurethanes were synthesized.

Phosphorus-containing polyamide-imides were prepared from N,N'-bis(4-carboxyphthalimido)-3,Y-diphenylalkylphosphine oxide and aromatic diacetamido derivatives by acidolysis; the reaction conditions are discussed. The resulting polymers were fairly soluble in DMA, DMF and conc. H2SO4; the reduced vis
