PURPOSE:To prepare a polyamide resin having improved moldability, capable of molding articles with excellent impact rsistance on moisture absorption, and surface properties, comprising a specific modified silicone oil. CONSTITUTION:A polyamide, e.g. polycaprolactam or polyhexamethylene sebacamide, is incorporated with about 0.5-25 wt.%, preferably 1-15 wt.%, of a modified silicone oil having an epoxy or hydroxyl group equivalent of about 500- 4,000 and a viscosity at 25 deg.C >= 1,000 CSt. Preferably, the silicone oil is melt kneaded with a molten polyamide at the last stage or completion of the polymerization, or with molten polyamide chips. |
