Zusammenfassung:	To provide a polyurethane foam-forming composition capable of producing a polyurethane foam excellent in flame retardancy without deteriorating moldability.SOLUTION: The polyurethane foam-forming composition contains: a halogen-containing polyether polyol represented by formula (1) and having a number average molecular weight of 500 or more and 5,000 or less and a degree of unsaturation of 0.020 meq/g or less; an isocyanate compound; and a foaming agent. (In the formula (1), m represents an integer of 2-8, R1 represents an active hydrogen-containing compound residue, and X represents a halogen atom.)SELECTED DRAWING: None 【課題】成形性を低下させることなく、難燃性に優れたポリウレタンフォームを製造することができるポリウレタンフォーム形成性組成物。【解決手段】式（１）で示される、数平均分子量が５００以上５，０００以下で、かつ、不飽和度が０．０２０ｍｅｑ／ｇ以下のハロゲン含有ポリエーテルポリオールと、イソシアネート化合物、及び発泡剤を含有するポリウレタンフォーム形成性組成物。（上記式（１）中、ｍは２〜８の整数、Ｒ１は活性水素含有化合物残基、Ｘはハロゲン原子を表す。）【選択図】なし
