摘要: Abstract Fire retardant efficiency of aryl phosphates in combination with phenol-formaldehyde novolac type resin was studied poly(butylene terephthalate) (PBT). It shown that resorcinol bis(diphenyl phosphate) or bisphenol A is an efficient fire non-glass reinforced PBT. Co-addition triphenyl phosphate required for glass-reinforced PBT to reach similar performance. Apparently phosphates/novolac prevent exudation the surface and facilitate crystallization Although are compatible do not decompose polymer during compounding, exhibited some reduction Izod impact strength heat distortion temperature. These phenomena were attributed changes crystalline morphology, probably also amorphous regions polymer.
