摘要:
A polyamide, a copolyamide, or a polyamide blend is reacted with a monoepoxy-functional phosphorus compound at an elevated temperature to produce flame-retardant polyamides, where the amount of phosphorus compound is 5 wt % to 35 wt %, based on the total composition, i.e., the polyamide mixture.
