The antimony‐containing polymer of bisphenol‐A (BPA) and triphenyl antimony dinitrate was used as a flame retardant (FR) for chloroprene rubber (CR) and natural rubber (NR). The flame retardancy of this additive was monitored by the limiting oxygen index (LOI) measurements of the rubber vulcanizates and compared with that for antimony trioxide used as a FR additive. The thermogravimetric analysis (TGA) of the vulcanizates has also been studied. A structure flammability relationship has been established. The effect of this FR additive on physical properties of the vulcanizates undergoing heat aging and solvent leaching has also been evaluated. © 1998 John Wiley & Sons, Inc.
