  • Patent number: 6733854
    Abstract: Disclosed are a polyamide resin composition and a synthetic resin product prepared therefrom. The polyamide resin composition comprises 30-95 parts by weight of polyamide resin, 1-45 parts by weight of impact resistant component, 0.1-20 parts by weight of nylon plasticizer, 0.01-5 parts by weight of nylon thickener having at least two functional groups at the ends of its polymer chain and 0.5-10 parts by weight of core-shell rubber. Such composition is advantageous in light of much lower preparation cost, while retaining higher flexibility, moldability and excellent external appearance, compared to conventional nylon elastomer reinforced polyamide resin composition. Thereby, the composition can be effectively applied to internal or external decorative articles for motor vehicles and electrical or electronic components.
