| titleOfInvention | Fusible polyimide molding compound and method for preparing the same |
| abstract | The present invention provides a method for preparing a fusible polyimide molding compound, which includes the following steps: (Step 1) Preparation of a polyamic acid solution: 2, 3, 3 ′, 4 ′ -ODPA and oxydianiline are introduced into an aprotic polar solution at an equimolar ratio, and both substances are reacted at room temperature for 3 to 5 hours to prepare a polyamic acid solution; (Step 2) Chemical imidization: To 100 parts by weight of the polyamic acid solution, 40 to 160 parts by weight of a dehydrating agent and 5 to 50 parts by weight of a tertiary amine organic alkali catalyst are added together with a polyamide precipitating agent such as nonpolar arene, and 0.5 to 2 hours. Stir at high speed to complete chemical imidation; prepare a polyamide molding powder via filtration. Compared to s-polyamide, a-polyamide can lower the molding temperature by 70 ° C, the mechanical properties of a-polyamide at 220 ° C are superior to s-polyamide, and a-polyamide is soluble and fusible. . |
