抄録

Phosphorus-containing bisester-diphthalic acids, 4, 4′- [alkyl-phosphorylbis (1, 3-phenyleneoxycarbonyl)] diphthalic acid (III), were synthesized from bis (3-hydroxyphenyl) alkylphosphine oxide and trimellitic anhydride acid chloride and polyester-imides were prepared from III and aromatic diisocyanates. The polymerization conditions are examined. The resulting polymers were soluble in DMA, DMF, DMSO, and concd. H2SO4. They had reduced viscosities of 0.09-0.23dl/g measured at a concentration of 0.2 g/dl in DMA at 30°C. The polymer yields were 40-76%. Thermal analyses showed that the polymers degraded in three steps in air and in two stages in nitrogen and that the thermal behaviors of phosphorus-containing polymers were different from those of analogous nonphosphorus polymers. The phosphorus-containing polymers had a little better flame-retardance than nonphosphorus polymers.
