(EN) METHOD FOR PRODUCING FORMALDEHYDE-POOR POLYOXYMETHYLEN
(FR) PROCEDE DE PRODUCTION DE POLYOXYMETHYLENE PAUVRE EN FORMALDEHYDE
Abstract: front page image
(DE)Kontinuierliches Verfahren zur Herstellung von Formaldehyd-armen Polyoxymethylen- homo- oder -copolymeren unter Mitverwendung mindestens eines Formaldehydfän gers und mindestens eines Antioxidans, dadurch gekennzeichnet, dass mindestens 50 Gew.-% der Formaldehydfänger-Gesamtmenge erst dann zugefügt wird, wenn zu vor bereits mindestens 80 Gew.-% der Antioxidans-Gesamtmenge zugefügt wurde.
(EN)The invention relates to a method for continuously producing homopolymers or copolymers of a formaldehyde-poor polyoxymethylen using at least one type of formaldehyde catcher and at least one type of antioxidant, wherein at least 50 % by weight of the total formaldehyde catcher content is added when at least 80 % by weight of the antioxidant is already added.
(FR)Procédé en continu de production d'homopolymères ou de copolymères de polyoxyméthylène pauvres en formaldéhyde, avec utilisation d'au moins un absorbeur de formaldéhyde et d'au moins un antioxydant, caractérisé en ce qu'au moins 50 % en poids de la quantité totale d'absorbeur de formaldéhyde ne sont ajoutés que si l'on a ajouté préalablement au moins 80 % en poids de la quantité totale d'antioxydant.
