PURPOSE: To provide a polyamide compsn. having excellent sliding properties, dimensional stability, heat resistance, etc. as well as improved arc resistance and suitable for use as a material for the production of electrical parts, by blending melamine cyanurate and ore powder with a polyamide. n CONSTITUTION: 0.01W6wt% melamine cyanurate obtd. by the addition reacion of melamine with an equimolar amount of cyanuric acid, and 10W60wt% are powder such as talc, kaolin or mica are blended with a polyamide such as nylon 6 or nylon 66. The mixture is melt-mixed in a kneader, etc. to obtain the desired polyamide resin having improved arc resistance. Alternatively, melamine and an equimolar amount of cyanuric acid are blended with a monomer mixture for the production of the polyamide, and the mixture is polymerized in the presence of water with heating. The resulting melamine cyanurate-contg. polyamide and ore powder are melt-mixed in a kneader to produce the desired polyamide compsn. n COPYRIGHT: (C)1984,JPO&Japio |
