  • Patent number: 10336904
    Abstract: A resin blend composition of a polyamide resin and a polyester resin is described, which includes a polyamide resin, a polyester resin and an epoxy resin. The resin blend composition can have improved compatibility between the polyamide resin and the thermoplastic polyester resin, and therefore mechanical properties (strength, bending strength, elasticity, abrasion resistance, impact strength), chemical properties (solvent resistance), thermal resistance, dimensional stability, and paintability.

  • Patent number: 9765217
    Abstract: The present invention relates to a composition comprising at least a thermoplastic polyamide resin, a thermoplastic polyester resin, a reinforcing or bulking filler and a fire retardant. Said composition does not comprise any compatibilizer for the polyamide and the polyester, such as an agent of polymeric type, and especially no epoxy resin. Such a fire-retardant polyamide/polyester composition shows good compatibility and good mechanical and fire-retardant properties, especially a good capacity not to form flames in the presence of glowing agents, for example in the field of domestic electrical appliances, electrics and electronics.

  • Publication number: 20150080534
    Abstract: The present invention concerns a method of preparing a hybrid fiber including polyamide and polyester. Particularly, the method of preparing a hybrid fiber comprises, forming a blend by melting a) 4.99 to 95% by weight of a thermoplastic polyamide resin, b) 4.99 to 95% by weight of a thermoplastic polyester resin, and c) 0.01 to 10% by weight of an epoxy resin at 250 to 300° C., and blend spinning and elongating 10 to 90% by weight of the blend with 90 to 10% by weight of a polyester resin. The hybrid fiber shows highly improved compatibility of the polyamide resin and the thermoplastic polyester resin, and shows excellent strength and elongation.
