Method for production of stable polyoxymethylene copolymers (CPOM)

The present invention relates to a method for the deactivation of an acid catalyst during the production process of a polyoxymethylene copolymer (cPOM) by adding triisopropanolamine (tris(2-hydroxypropyl)amine) to a mixture which comprises the polyoxymethylene copolymer (cPOM) and the acid catalyst....

Beschreibung
Zusammenfassung:	The present invention relates to a method for the deactivation of an acid catalyst during the production process of a polyoxymethylene copolymer (cPOM) by adding triisopropanolamine (tris(2-hydroxypropyl)amine) to a mixture which comprises the polyoxymethylene copolymer (cPOM) and the acid catalyst. 本发明涉及一种在聚甲醛共聚物(cPOM)的制备方法中通过将三异丙醇胺(三(2-羟丙基)胺)加入到包含聚甲醛共聚物(cPOM)和酸催化剂的混合物中使酸催化剂失活的方法。
