Description
本発明は、モノマー、特に、共役ジエンおよび/またはビニル芳香族炭化水素を、炭化水素溶媒中でアニオン重合する方法に関する。より詳細には、本発明は、ポリマーセメント(炭化水素溶媒中のアニオンポリマーの溶液)の粘度を低下させることによって製造システムの処理量を増大させるこうした方法の改善に関する。
共役ジエンおよび/またはビニル芳香族炭化水素のポリマーを含むアニオンポリマーは、非常に多くの方法によって製造されている。しかし、アニオン重合開始剤のもとでのこうした、またはその他のモノマーのアニオン重合が最も広範に用いられる工業的方法である。こうした重合は、ヘキサン、シクロヘキサンまたはトルエンなどの不活性溶媒中で実施され、重合開始剤は、通常、有機アルカリ金属化合物、特に、アルキルリチウム化合物である。用いられる溶媒は、ほとんど常に非極性炭化水素であり、これは、こうした溶媒がこうしたモノマーのポリマー、特に共役ジエンポリマー、またはブロック共重合体の一部を形成する際のブロックに対して極めて良好な溶媒であるからである。
本発明は、モノマーを有機置換アルカリ金属化合物であるアニオン重合開始剤とモノマーを接触させることによってモノマーをアニオン重合する既知の方法に対する改善である。本改善は、重合開始前または開始時にアルキル金属を添加する場合、アルカリ金属開始剤1当量あたり少なくとも0.01当量のアルキル金属化合物を添加することによって、ポリマーセメントの粘度を低下させることを含む。重合中または重合後、しかしリビングポリマーを停止させる前にアルキル金属を添加する場合には、リビングポリマー鎖末端(すなわち、スチリル−リチウムまたはジエニル−リチウム部分)1当量あたり少なくとも0.01当量のアルキル金属化合物を用いるべきである。好ましくは、両方の場合に、0.01〜1.5当量、最も好ましくは0.01〜1.0当量を用いる。
本発明は、モノマーを単官能価アニオン重合開始剤、一般にはリチウム開始剤と接触させることによって、モノマーをアニオン重合する方法に関する。ナトリウムまたはカリウム開始剤も用いることができる。例えば、本発明に従って製造することができるポリマーは、スチレン、ジエンとのランダムおよびブロック共重合体、ポリエーテルポリマー、ポリエステルポリマー、ポリカーボネートポリマー、ポリスチレン、ポリアクリレート、ポリメタクリレートなどを含むあらゆるアニオン重合性モノマーからのポリマーである。下記ポリスチレンポリマーは、ポリジエンポリマーと同じように製造してもよいし、ジエンとのランダムまたはブロック共重合体であってもよい。
(式中、Rは、1〜約20個の炭素原子を有する脂肪族、脂環式、芳香族またはアルキル置換芳香族炭化水素基であり、nは、1〜4の整数である)を有する有機リチウム化合物である。有機リチウム開始剤は、高温で安定度が増すので、より高い温度での重合に好ましい。
LiとAlの間のアルキル中心の分布に関する選択規則
実施例1
一般手順を用いて、適量のトリアルキルアルミニウムを添加することによって、リビングアニオン重合溶液の粘度をいかに有意に低下させることができるかを実証した。スチレン−イソプレン−イソプレン−スチレントリブロック(SIIS)とイソプレン−スチレンジブロック(IS)のブロック共重合体をシクロヘキサン中で段階を追って合成した。実験中、トリアルキルアルミニウムの添加前および後の多数の操作条件における異なる時点で、粘度データを採取した。リビングポリマー溶液の粘度は、毛細管装置を用いてその場で測定した。粘度測定は、反応器の操作圧および温度を記録しながら、測定時間に、有限量のポリマー溶液に圧力をかけて、毛細管を通してサンプルビンに入れることによって行った。
一系列のポリマー、大部分がスチレンとブタジエンのブロック共重合体、をよく制御された条件のもとで調製した。アニオン重合反応は、一定温度で、5重量%の初期モノマー濃度で分子量5,000のポリマーセグメントを作るために十分なモノマー充填量を目標とする各重合段階(ブロック合成)を伴った。
Claims (1)
- 共役ジエン及びビニル芳香族炭化水素(極性モノマーを除く)を適する炭化水素溶媒中でケイ素系官能基保護開始剤以外の有機置換アルカリ金属化合物である単官能価アニオン重合開始剤と接触させることによって共役ジエン及びビニル芳香族炭化水素のモノマーをアニオン重合して、リビングポリマーセメントを生成する方法であって、その改善が、重合中または後に、リビングポリマー鎖末端1当量あたり少なくとも0.01当量のアルキル金属化合物をセメントに添加することによってポリマーセメントの粘度を低下させることを含み、この場合、アルキル金属化合物のアルキル基は、それらがリビングポリマー鎖末端と交換しないように選択され、該単官能価アニオン重合開始剤はリチウム、ナトリウム、またはカリウム開始剤であり、該アルキル金属化合物はトリエチルアルミニウム、トリメチルアルミニウム、トリ−n−プロピルアルミニウム、トリ−n−ブチルアルミニウム、トリイソブチルアルミニウム、トリ−n−ヘキシルアルミニウム、トリオクチルアルミニウム、ブチルエチルマグネシウム、ジ−n−ブチルマグネシウム、ジ−n−ヘキシルマグネシウム、ジメチル亜鉛、ジエチル亜鉛、ジ−n−プロピル亜鉛、ジイソブチル亜鉛およびジ−n−ブチル亜鉛から成る群から選択される方法。
