Abstract: There is provided a direct method for producing a reinforced composite resin material by polymerizing a specific copolyester having high heat resistance and a reinforcing effect in the presence of a molten preformed thermoplastic polymer. In the production of the reinforced composite resin material, a fibrillar copolyester is produced by the polymerization of specific hydroxy aromatic carboxylic acid monomers and is generated within a molten preformed thermoplastic polymer while undergoing a shearing stress. Such shearing stress causes the formation of the requisite fibrous reinforcement preferably having an aspect ratio of at least 3 within the preformed thermoplastic polymer. Such hydroxy aromatic carboxylic acid monomers preferably have acetylated hydroxyl groups when copolymerized. Additionally, substituents other than hydrogen atoms optionally may be present on the rings of the aromatic monomers at the time of the copolymerization to form the fibrillar copolyester.
