POLYAMIDE BASED POLYMER COMPOSITIONS HAVING HIGH FLOWABILITY AND MECHANICAL STRENGTH AND POLYAMIDE BASED COMPOSITE COMPRISING THE SAME

摘要

The present invention provides a polymer composition comprising: 20-90 wt% of a polyamide-based resin; 10-80 wt% of a glass fiber; and p-phenylene bis stearamide as a flowability adjustment agent. The polymer composition according to the present invention utilizes a flowability adjustment agent, which is p-phenylene bis stearamide, to reduce friction between a melted resin and a processing apparatus, and effectively disperses the polyamide-based resin and the glass fiber, thereby significantly reducing torque. Accordingly, composite materials prepared from the polymer composition of the present invention can be advantageously applied to compounding or injection-molding of a polyamide-based engineering plastic having a high content of glass fibers.
