[Claims]
1. An organotin-based catalyst such as tin octylate or dibutyltin oxide or dibutyltin dilaurate in an amount of 0.0001 to 0.001% by weight based on an initiator having active hydrogen comprising a polyhydric alcohol or a polyhydric amine. A lactone-based polyol obtained by subjecting a lactone monomer to a ring-opening polymerization reaction at a reaction temperature of 165 ° C. to 175 ° C. and terminating the reaction when the lactone monomer becomes 0.5% by weight or less, the reaction in the polyol A method for producing a lactone-based polyol, wherein the total amount of the by-product cyclic ester compound is 0.5% by weight or less.
2. A polyurethane resin using the lactone-based polyol obtained by the production method according to claim 1.
即ち、本発明は、多価アルコール又は多価アミンからなる活性水素を有する開始剤に対し、有機スズ系触媒であるオクチル酸スズ又はジブチルスズオキサイド又はジブチルスズジラウレート０．０００１〜０．００１重量％の存在下で、ラクトンモノマーを反応温度１６５℃〜１７５℃で開環重合反応させ、ラクトンモノマーが０．５重量％以下になった時点で反応を終了させて得られるラクトン系ポリオールで、そのポリオール中の反応副生成物である環状エステル化合物が、トータル量で０．５重量％以下であることを特徴とするラクトン系ポリオールの製造方法を提供するものである。また、このポリウレタン樹脂用ラクトンポリオールを用いることにより強度物性低下、ブレード抑制や糸切れ防止を可能にした優れたウレタン樹脂を提供するものである。 That is, the present invention relates to the presence of 0.0001 to 0.001% by weight of an organotin-based catalyst, tin octylate or dibutyltin oxide or dibutyltin dilaurate, based on an initiator having active hydrogen composed of a polyhydric alcohol or a polyamine. A lactone-based polyol obtained by subjecting a lactone monomer to a ring-opening polymerization reaction at a reaction temperature of 165 ° C. to 175 ° C. and terminating the reaction when the lactone monomer becomes 0.5% by weight or less, An object of the present invention is to provide a method for producing a lactone-based polyol, wherein the total amount of the cyclic ester compound as a reaction by-product is 0.5% by weight or less. It is another object of the present invention to provide an excellent urethane resin capable of reducing strength properties, suppressing blades and preventing yarn breakage by using the lactone polyol for a polyurethane resin.
本発明の触媒としては、例えば、オクチル酸スズ、ジブチルスズオキサイド、ジブチルスズジラウレートが挙げられる。無機系スズ触媒は、有機系スズ触媒に比べ、活性が強く、開環重合のコントロールが困難である。また、ラクトン系ポリオールを溶融状態で貯蔵した場合、その活性により、重合反応の進行および環状エステル化合物の生成を引き起こし、増加させてしまうため、有機スズ系触媒の方がより好ましい。
The catalyst of the present invention, for example, tin octylate, dibutyltin oxide, and dibutyltin dilaurate. Inorganic tin catalysts have higher activity than organic tin catalysts, and it is difficult to control ring-opening polymerization. In addition, when the lactone-based polyol is stored in a molten state, the activity of the lactone-based polyol causes the polymerization reaction and the formation of a cyclic ester compound to be caused to increase, so that an organotin-based catalyst is more preferable.
