Abstract  

For many applications poly(styrene) must be treated to reduce its flammability. This is usually done by incorporating a flame retardant additive, usually an organohalogen compound, into the formulation as the polymer is being processed. A potentially very efficient way of introducing flame retardance would be to incorporate a suitable structural unit directly into the polymer. This can be done by using 2,4,4,5,5-pentaphenyl-1,3,2-dioxaphospholane as an initiator for styrene polymerization. The strained carbon–carbon bond of the phospholane undergoes homolysis at moderate temperatures to generate a diradical which initiates polymerization. The resulting polymer contains an O–P–O unit in the mainchain. Thermogravimetry indicates that the thermal stability of the polymer is quite comparable to that of poly(styrene) generated by conventional methods.
