摘要

Phosphorus containing polyamides and copolyamides were prepared from 1-(dialkoxyphosphinyl)methyl-2,4- and -2,6-diaminobenzenes. The polymers produced were characterized by infrared and proton nuclear magnetic resonance spectroscopy, differential scanning calorimetry, and thermogravimetric analysis. Their thermal properties were compared with those of the corresponding common polyamides. In addition, by determining the limiting oxygen index value of some of these polyamides, their fire resistance was evaluated.
