Abstract
A crystalline terpolymer polyamide produced from: (a) an equimolar salt of hexamethylenediamine with adipic acid, (b) an equimolar salt of hexamethylenediamine with terephthalic acid, and (c) 12-aminododecanoic acid or .omega.-laurolactam; a polyamide resin composition comprising (A) the terpolymer polyamide and (B) a modified polyolefin; a polyamide resin composition comprising (A) the terpolymer polyamide, (B) the modified polyolefin, and (C) polyamide 12; a polyamide resin composition comprising (A) the terpolymer polyamide and (D) an inorganic filler and/or a flame retardant; and an automotive part comprising a molding one of these terpolymer polyamide and polyamide resin compositions.
Claims12
A crystalline terpolymer polyamide produced from and consisting essentially of:
- (a) 20 to 80% by weight of an equimolar salt of hexamethylenediamine with adipic acid,
- (b) 20 to 80% by weight of an equimolar salt of hexamethylenediamine with terephthalic acid, and
- (c) 1 to 30% by weight of 12-aminododecanoic acid or .omega.-laurolactam.
A polyamide resin composition consisting essentially of
- from 65 to 95% by weight (A) a crystalline terpolymer polyamide produced from:

- from 5 to 35% by weight (B) a modified polyolefin produced by graft-polymerizing an .alpha., .beta.-unsaturated carboxylic acid or an anhydride or derivative thereof with a polyolefin.
A polyamide resin composition consisting essentially of
- (A) a crystalline terpolymer polyamide produced from:
- (a) an equimolar salt of hexamethylenediamine with adipic acid, (b) an equimolar salt of hexamethylenediamine with terephthalic acid, and (c) 12-aminododecanoic acid or .omega.-laurolactam and
- (D) at least one component selected from the group consisting of an inorganic filler and a flame retardant.
