Synthesis of Alkyl and Aryl Phosphazene High Polymers

Abstract: : The first stable, high molecular weight phosphazene polymers that contain alkyl- or aryl- groups bonded directly to phosphorus have been synthesized by the interaction of organolithium or dialkylmagnesium reagents with poly-(difluorophosphazene). The polymers are elastomers or tough, flexible, film-forming materials.

Poly(organophosphazene) – ungewöhnliche neue Hochpolymere

Abstract: Ein hochpolymeres System mit einem aus alternierenden Phosphor- und Stickstoffatomen aufgebauten anorganischen Gerust verspricht viele der Probleme zu losen, die bei konventionellen organischen Polymeren auftreten Der folgende Aufsatz gibt einen Uberblick uber die Chemie, die Struktur sowie die biomedizinischen und technologischen Aspekte dieser Polymere

Complex or salt of a platinum (II) compound and a nitrogen containing polymer

Abstract: A cis- complex or -salt of a square planar platinum compound and a nitrogen containing oligomer or polymer prepared by reacting a platinum (II) compound with a nitrogen containing oligomer or polymer in an organic solvent or an acidic aqueous medium, said complex or salt being useful for treating animal malignant tumor cells sensitive to cis-square planar platinum compounds.
