Abstract
PURPOSE: To obtain title compsn. useful for powder coating by keeping stably desired polymn. degree to obtain the compsn. in low polymn. degree by adding phosphoric acid to polyamide resin, melting the mixt. with heating, kneading the mixt. and then blending polymn. stabilizer with the mixt.
CONSTITUTION: (B) Phosphoric acid or a derivative thereof and, if necessary, (C) water are added to (A) polyamide resin. The mixt. is molten with heating and kneaded until the desired polymn. degree is obtained. The mixt. is pelleted. (D) A polymn. stabilizer selected from ZnO, Al2O3, stearic acid and metal salts thereof is added to pellets. The mixt. is mixed in Henschel mixer and ground to obtain the desired polyamide resin compsn. Polyamide resins having relatively high polymn, degree such as nylon 11 as (A) are used. An example of the derivative of (B) is trimethyl phosphate. From 0.1 to 1.0pts.wt. of (B) and from 0.1 to 5.0pts.wt. of (D) are used based on 100pts.wt. of (A).
