METHOD OF PRODUCING LOW-VISCOSITY POLYAMIDE RESIN COMPOSITION AND LOW-VISCOSITY POLYAMIDE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a method of producing a low-viscosity polyamide resin composition, and to provide the low-viscosity polyamide resin composition which is excellent in handleability and safety during production while reducing its production cost and has excellent adhesive strength and heat resistance.;SOLUTION: The method includes: a step of adding a trivalent or more polyalcohol to a high-viscosity polyamide resin composition having a viscosity number of 80-300 ml/g and heating and kneading the resultant mixture, thereby lowering the viscosity number to generate a low-viscosity polyamide resin composition having the viscosity number of 40-150 ml/g; a step of cooling the low-viscosity polyamide resin composition; and a step of drying the low-viscosity polyamide resin composition.;COPYRIGHT: (C)2012,JPO&INPIT
