Conclusions

  1. 1.

    Mixed polyamides were prepared by reaction between the 1,6-hexanediamine and 1,8-octanediamine salts of 3,3′-(phenylphosphinylidene)dipropionic acid on the one hand and 1,6-hexanediamine adipate, azelaate, and sebacate on the other, and also between 1,6-hexanediamine adipate and an equimolecular mixture of adipic acid and 3,3′-(phenylphosphinylidene)bispropylamine.

  2. 2.

    Polyamides with a relatively low phosphorus content are crystalline, whereas those with a pre-dominance of the phosphorus-containing component are amorphous. For intermediate contents of the phosphorus component the amorphous samples may crystallize during heating in the course of the recording of the TM curves.

  3. 3.

    With increase in the proportion of the phosphorus-containing component the melting points of the crystalline polyamides investigated fall, whereas for amorphous samples the flow temperatures rise somewhat under the same circumstances.

  4. 4.

    Mixed polyamides containing 5% and more of phosphorus are self-extinguishing on withdrawal from a flame.
