A process for producing flame-retardant shaped articles of thermoplastic synthetic resins is disclosed which process comprises dispersing homogeneously in a thermoplastic synthetic resin an inorganic metal compound and a surfactant, said inorganic metal compound being one capable of forming a hydrate by reacting with a member of the group consisting of water and an aqueous acid solution, forming the resulting composition into a desired shaped article, and thereafter contacting the thus obtained shaped article with a member selected from the group consisting of water and an aqueous acid solution, thereby converting said inorganic metal compound contained in said shaped article to a hydrate.
