Phosphate-polyester copolymers were synthesized from spirocyclic pentaerythritol di(phosphate acid monochloride)s (SPDPC), which is an intumescent, phosphate flame retardant. Because of the new monomer being introduced, the structure and properties of the polyester were altered. The effects of the p

Phosphorus containing polyimides were prepared via phosphorylation of organosoluble polyimides. This was achieved by phenoxaphosphine oxide ring formation reaction or esterification with diethylchlorophosphate. The phosphorylation was confirmed by infrared, 31 P nuclear magnetic resonance, and eleme
## Abstract A novel intumescent flame retardant: tetraβspirophosphorylβbenzoguanamine (TSPB) containing three constituents was used as a new flame retardant for polypropylene to prepare flameβretardant materials, whose flammability and thermal behavior were studied by the limited oxygen index (LOI)
