Abstract: PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition which gives a sheet hardly exhibiting warpage, etc., even when embossed and which exhibits excellent mold release characteristics in card production by compounding a thermoplastic resin with specified amounts of an inorganic platy filler having a specified average particle size and a mold release agent. SOLUTION: This composition is prepared by compounding 100 pts.wt. thermoplastic resin with 0.5-25 pts.wt. inorganic platy filler having an average particle size of 0.5-20 μm and 0.01-5 pts.wt. mold release agent. Preferably, the thermoplastic resin has a total light transmission (per 2 mm thickness, according to ASTM D1003) of 50% or higher and/or a glass transition temperature of 70-170 deg.C. Preferable examples of the thermoplastic resin are PS, a styrene- acrylonitrile copolymer, a styrene-butadiene-acrylonitrile terpolymer, a polyester, and a polycarbonate. Talc is preferable as the inorganic platy filler. Preferably, at least one mold release agent selected from among montanic acid compounds and low-molecular polyolefins is used.

Abstract: PROBLEM TO BE SOLVED: To improve the mechanical characteristics, hydrolyzability and moldability by blending a polybutylene terephthalate, reinforcing fibers and an epoxy compound so that the reinforcing fibers in the composition have a specified relation between the weight-mean fiber length and the fiber diameter and a specified ratio of the weight-mean fiber length to the number-mean fiber length. SOLUTION: The polybutylene terephthalate (A) is obtained by the polycondensation of the principal constituents comprising terephthalic acid or its ester-forming derivative, and 1,4-butane diol and its ester-forming derivative. The reinforcing fibers (B) comprise those usually used for reinforcing a resin, and having a diameter of 4-25μm. The relation between the weight-mean fiber length(Lw) to the diameter-(d), in terms of the ratio Lw/d, is (50-250):1, and the ratio of the Lw to the number-mean fiber length (Ln), (Lw/Ln), is (1.1 to 3.5):1, preferably (1/1 to 2.0):1. The amount of component B blended is 1-60wt.% based on the total of components A and B. The epoxy compound (C) is blended in an amount of at most 2.5 pts.wt. based on 100 pts.wt. total of components A and B.

Abstract: PURPOSE:To eliminate an unstable flow of an extruded piece of a fiber- reinforced thermoplastic resin structure to obtain an extruded piece free from surface roughness and superior in surface smoothness by mounting one or more planar plates in a cylinder between a screw top and a die in an extruder. CONSTITUTION:A planar plate 1 is mounted in an extruder cylinder barrel 4 frontward of screws 5 of a twin-screw extruder or in an adapter 3. A spiral flow of a melt mixture extruded by the screws 5 is corrected by the planar plate 1, thereafter being delivered from a delivery port 6 of a die 2 mounted on the extruder directly or through the adapter 3. Therefore, when a fiber- reinforced thermoplastic resin structure is extruded from the die of the extruder, abnormal flow of the structure is suppressed, and the surface state of the extruded piece is improved. Thus, the fiber-reinforced thermoplastic resin structure superior in surface smoothness can be produced.
