Abstract
A method for producing thermoplastic resin molded articles is disclosed. The method comprises heating a sheet comprising a crystalline thermoplastic resin, which is crosslinked to a degree of more than about 5%, to a temperature that is higher than the melting point of the crosslinked resin but below the decomposition temperature thereof. The thus pre-heated sheet is press-molded under a pressure of about 50-1,000 kg/cm.sup.2 by a pair of press mold dies, which are maintained at a temperature below the melting point of the crosslinked resin.
