Description
ポリマー上のカチオン電荷が安定化され、ポリマー中で更なる反応が阻止される、
この物質がホルミエート末端基と反応することがあり、これによりポリマーの不安定な末端基が結合する、
ホルムアルデヒド捕捉剤およびラジカル捕捉剤として使用できる、
多くの反応可能性によりこの物質が主にポリマーに結合して存在する。この場合に、例えば揮発性有機モノマー(すなわち未反応塩基)を分離しなくてよいので、ポリマーの後処理の際に利点が生じる。
式中、Zは化学結合、−O−、−ORO−であり、RはC1〜C8−アルキレンまたはC3〜C8−シクロアルキレンである。
粒度分布はシーブの標準セット(DIN4188によるシーブ分析)にもとづき種々のシーブ部分に分かれ、これらの部分を計量する。
a)重合容器、有利にタンク(カスケード)に直接添加して沈殿した(粒子の形の)POMを生じることにより、または
b)溶剤からPOMポリマーを完全に分離し、引き続き気体の失活剤で処理した後に、または
c)溶剤を部分的に除去し、沈殿したポリマーが含まれる残りの溶剤に失活剤を添加した後に、または
d)溶剤からポリマーを完全に分離し、適当な溶剤にポリマーを溶解し、溶解したポリマーに失活剤を添加した後に、
少なくとも1種の失活剤d)を添加することにより失活する。
a)反応溶融物に純粋な物質または溶液または懸濁液の添加により、
b)有利に補助的押出機または充填スクリューにより反応溶融物に物質を添加することにより行う。
記載される%はすべて質量%である。
トリオキサン94%、ジオキソラン6%およびブチラール0.01%からなるモノマー混合物を、1.5l/hの体積流量速度で、連続的に重合反応器(静的混合機を有する管状反応器、T=175℃)に供給した。開始剤1ppmを溶液(70%、トリグリムに溶解した過塩素酸水溶液、1%)の形でモノマー流に注入し、反応混合物をコイル状管形反応器中で静的混合機を使用して緊密に混合した。重合区間4m後方で、失活剤d)の水溶液(表参照)を1%でポリマー溶融物に注入し、開始剤に対して得られた停止剤の過剰モルは20倍であった。約3分の滞留時間後にポリマー溶融物を排出した。
Claims (7)
- 失活剤d)として、4−アミノ−2,2,6,6−テトラメチルピペリジンを使用する請求項1記載の方法。
- 開始剤b)0.001〜1000質量ppmを使用する請求項1または2記載の方法。
- 失活剤d)0.001〜500質量ppmを使用する請求項1から3までのいずれか1項記載の方法。
- 開始剤b)に対して失活剤d)を200:1〜0.1:1の割合で使用する請求項1から4までのいずれか1項記載の方法。
- 一般式Iの少なくとも1個の塩基性化合物d)から誘導される単位0.001〜100質量ppmを含有する請求項1から5までのいずれか1項記載の方法により得られるポリオキシメチレンホモポリマーまたはコポリマー。
- 鎖の0.001〜30%が失活剤d)から誘導される単位を有する請求項6記載のポリオキシメチレンホモポリマーまたはコポリマー。
