Abstract: Flame-retardant polybenzoxazine foams containing 1% phosphorus were prepared from diphenolic acid-based benzoxazine and 9,10-dihydro-9-oxa-10-(1-hydroxy-1-methylethyl)phosphaphenanthrene-10-oxide. Statistical predictive models were developed to determine the influence of the foaming time (tf) and foaming temperature (Tf) on the density, compressive modulus, and compressive strength of the foams. Results showed that the density of the foams exhibited great dependence on tf, whereas both compressive properties were more dependent on Tf and tf. Additionally, the flammability of the foams was also characterized by the limiting oxygen index. The presence of 9,10-dihydro-9-oxa-10-(1-hydroxy-1-methylethyl)phosphaphenanthrene-10-oxide greatly improved the flame retardancy of the resulting foams. © The Author(s) 2015.
