Description
本発明は、精製された不飽和基含有ポリエーテル重合体の製造方法、及び加水分解性ケイ素基含有ポリエーテル重合体の製造方法に関する。 The present invention relates to a method for producing a purified unsaturated group-containing polyether polymer and a method for producing a hydrolyzable silicon group-containing polyether polymer.
従来より、加水分解性ケイ素基含有ポリエーテル重合体とシラノール縮合触媒を含有する室温硬化性組成物を、シーリング材、接着剤等として利用する方法はよく知られており、工業的に有用である。
このような加水分解性ケイ素基含有ポリエーテル重合体を製造する方法の一例として、末端に水酸基を有するポリエーテル重合体を製造し、その末端水酸基をオレフィンへ変換した後、加水分解性ケイ素基を有するヒドロシラン化合物によりヒドロシリル化を行って製造する方法が挙げられる。
このため、末端水酸基がオレフィンへ変換された不飽和基含有ポリエーテル重合体が、加水分解性ケイ素基含有ポリエーテル重合体の中間体として重要である。
Conventionally, a method of using a room temperature curable composition containing a hydrolyzable silicon group-containing polyether polymer and a silanol condensation catalyst as a sealant, an adhesive, etc. is well known and is industrially useful. ..
As an example of a method for producing such a hydrolyzable silicon group-containing polyether polymer, a polyether polymer having a hydroxyl group at the terminal is produced, the terminal hydroxyl group is converted into an olefin, and then the hydrolyzable silicon group is obtained. Examples thereof include a method of producing by hydrosilylating with a hydrosilane compound having.
Therefore, an unsaturated group-containing polyether polymer in which the terminal hydroxyl group is converted into an olefin is important as an intermediate of the hydrolyzable silicon group-containing polyether polymer.
精製された不飽和基含有ポリエーテル重合体の製造方法としては、例えば、
1)ポリエーテル重合体の水酸基をメタルオキシ化により−OM基(MはNa又はK)に変換した後、−OM基と、アリルクロライド等のハロゲン化オレフィンとを反応させて、ポリエーテル重合体の末端基をオレフィンへ変換して、不飽和基含有ポリエーテル重合体の粗製品を得る工程と、
2)不飽和基含有ポリエーテル重合体の粗製品と、水と、アスコルビン酸又はその誘導体とを激しく混合した後、水層を分離して、油相より精製された不飽和基含有ポリエーテル重合体を回収する工程と、
を含む方法が知られている(特許文献1を参照)。
As a method for producing the purified unsaturated group-containing polyether polymer, for example,
1) After converting the hydroxyl group of the polyether polymer to a -OM group (M is Na or K) by metal oxylysis, the -OM group is reacted with a halogenated olefin such as allyl chloride to form a polyether polymer. To obtain a crude product of an unsaturated group-containing polyether polymer by converting the terminal group of
2) After vigorously mixing the crude product of the unsaturated group-containing polyether polymer, water, and ascorbic acid or a derivative thereof, the aqueous layer is separated and the unsaturated group-containing polyether weight purified from the oil phase. The process of collecting the coalescence and
(See Patent Document 1).
特許文献1に記載の方法によれば、確かに不飽和基含有ポリエーテル重合体中の金属量を低減させることができる。しかし、特許文献1に記載の方法では、不飽和基含有ポリエーテル重合体の粗製品を水で洗浄した後の分液時に、水相と油相との間に多量の中間相が生成する場合がある。 According to the method described in Patent Document 1, the amount of metal in the unsaturated group-containing polyether polymer can certainly be reduced. However, in the method described in Patent Document 1, a large amount of intermediate phase is generated between the aqueous phase and the oil phase when the crude product of the unsaturated group-containing polyether polymer is washed with water and then separated. There is.
かかる中間相は、水とともに有機成分を多量に含んでいるため、排水として処理する場合、活性汚泥槽等の負荷が高い。このため、中間相は、水層とは別に回収され、産業廃棄物として処理されることが多い。
中間相が多量に発生する場合、不飽和基含有ポリエーテル重合体の粗製品の水洗に用いた槽からの中間相の抜き出しに時間を要したり、中間相の産業廃棄物としての処理に多額の費用が生じたり、中間相を産業廃棄物処理業者に引き渡すまでに、中間相を保管するための広いスペースが必要であったり、種々の問題がある。
Since such an intermediate phase contains a large amount of organic components together with water, the load on the activated sludge tank and the like is high when treated as wastewater. For this reason, the intermediate phase is often collected separately from the aqueous layer and treated as industrial waste.
When a large amount of intermediate phase is generated, it takes time to extract the intermediate phase from the tank used for washing the crude product of the unsaturated group-containing polyether polymer with water, or it is expensive to treat the intermediate phase as industrial waste. There are various problems such as the cost of the intermediate phase and the need for a large space for storing the intermediate phase before it is handed over to an industrial waste treatment company.
本発明は以上の課題に鑑みなされたものであって、不飽和基含有ポリエーテル重合体の粗製品を水洗により精製するにあたって、洗浄後に水相と油相を分離する際に発生する中間相の量を低減できる精製された不飽和基含有ポリエーテル重合体の製造方法と、当該製造方法により製造される精製された不飽和基含有ポリエーテル重合体を用いる、加水分解性ケイ素基含有ポリエーテル重合体の製造方法と、を提供することを目的とする。 The present invention has been made in view of the above problems, and in purifying a crude product of an unsaturated group-containing polyether polymer by washing with water, the intermediate phase generated when the aqueous phase and the oil phase are separated after washing. A method for producing a purified unsaturated group-containing polyether polymer whose amount can be reduced, and a hydrolyzable silicon group-containing polyether weight using the purified unsaturated group-containing polyether polymer produced by the production method. It is an object of the present invention to provide a method for producing an union.

The method of allowing the mixture to stand is preferable from the viewpoint that the intermediate phase and the aqueous phase are not easily incorporated into the oil phase.
From the viewpoint that the oil phase can be efficiently recovered from the mixture in a short time, a method of applying centrifugal force to the mixture to separate the aqueous phase and the oil phase is preferable. Both of these methods can be performed in batch or continuous manner.

混合物の形成に有機溶剤(B)を用いていない場合、回収された油相を、そのまま、精製された不飽和基含有ポリエーテル重合体として用いることができる。
しかし、回収された油相がわすかに水を含む場合がある。この場合、加熱により、油相から水を除去してもよいし、無水硫酸ナトリウムや無水硫酸マグネシウムのような脱水剤を用いて脱水を行ってもよいし、ヘキサン、トルエン、キシレン等のエントレーナーを用いて共沸脱水を行ってもよい。
混合物の形成に有機溶剤(B)を用いる場合、油相は有機溶剤(B)を含む。このため、加熱により油相から有機溶剤(B)を留去することにより、精製された不飽和基含有ポリエーテル重合体が回収される。
このようにして回収される精製された不飽和基含有ポリエーテル重合体は、加水分解性ケイ素基含有ポリエーテル重合体の製造に好適に用いられる。
(Recovery of purified unsaturated group-containing polyether polymer)
When the organic solvent (B) is not used for forming the mixture, the recovered oil phase can be used as it is as a purified unsaturated group-containing polyether polymer.
However, the recovered oil phase may slightly contain water. In this case, water may be removed from the oil phase by heating, dehydration may be carried out using a dehydrating agent such as anhydrous sodium sulfate or anhydrous magnesium sulfate, or an entrainer such as hexane, toluene or xylene may be used. May be used for azeotropic dehydration.
When the organic solvent (B) is used to form the mixture, the oil phase contains the organic solvent (B). Therefore, the purified unsaturated group-containing polyether polymer is recovered by distilling off the organic solvent (B) from the oil phase by heating.
The purified unsaturated group-containing polyether polymer thus recovered is suitably used for producing a hydrolyzable silicon group-containing polyether polymer.
