Abstract

PURPOSE: To prepare the title composition having excellent uniformity, in high productivity, by mixing a linear saturated polyester resin having a specific intrinsic viscosity, a montan wax salt mixture containing uniformly dispersed fine powder of a solid inorganic compound, fine powder of an inorganic compound, and glass- fiber, with an extruder.
CONSTITUTION: A polyester resin molding compound is prepared by extruding a resin mixture composed of (A) 100 parts by weight of a linear saturated polyester resin having an intrinsic viscosity of 0.4W1.2 measured in 0-chlorophenol at 35°C, (B) 0.05W3 parts of montan wax containing a solid inorganic compound having a particle diameter of ≤20μ, (C) 0.01W200 parts of the above inorganic compound, and (D) 0W200 parts of glass-fiber. The weight ratio of the inorganic compound added to the montan wax to the montan was is ≥0.25. The addition of the inorganic compound to the montan wax facilitates the charging of the resin to the extruder, improves the extrusion stability, and increases the productivity.
