Abstract:
1. A process for producing a long-fiber-reinforced thermoplastic resin particle blend material (C) comprising dry blending 10 to 90 percent by weight of long-fiber-reinforced thermoplastic resin particles (A) comprising a thermoplastic resin (A 1 ) produced by using a metallocene catalyst, a modified polyolefin resin (A 2 ) modified with an unsaturated carboxylic acid or a derivative thereof, and reinforcing fibers (A 3 ), wherein the following requirements (1) to (5) are satisfied, and 90 to 10 percent by weight of polyolefin resin particles (B) for dilution, where the total of the long-fiber-reinforced thermoplastic resin particles (A) and the polyolefin resin particles (B) for dilution is assumed to be 100 percent by weight: (1) The amount of modification of the unsaturated carboxylic acid or a derivative thereof is 0.01 to 2 percent by weight in 100 percent by weight of the total of the thermoplastic resin (A (2) The total of the thermoplastic resin (A (3) The reinforcing fibers (A (4) When 25 g of the long-fiber-reinforced thermoplastic resin particles (A) are encapsulated in a 20-L chamber and are stood at 65° C. for 1 hour, the amount of acetaldehyde dissipated from the long-fiber-reinforced thermoplastic resin particles (A) is 3.0 μg/m (5) The melting point of the resin component in the long-fiber-reinforced thermoplastic resin particles (A) is 150° C. or higher.
