Title (EN) PROCESS FOR PREPARING POLYOXYMETHYLENE
(FR) PROCEDE DE PREPARATION DE POLYOXYMETHYLENE
Abstract: front page image
(EN)A process for preparing polyoxymethylene having an improved molten fluidity and an excellent workability by polymerizing formaldehyde using an anionic polymerization catalyst, which comprises using as a molecular weight modifier a polyhydric alcohol containing at least three alcoholic hydroxy groups to attain a desired molecular weight.
(FR)Un procede de preparation de polyoxymethylene ayant une fluidite de fusion amelioree et d"excellentes caracteristiques de travail en polymerisant de la formaldehyde en utilisant un catalyseur de polymerisation anionique, consiste a utiliser comme modificateur du poids moleculaire un alcool polyhydrique contenant au moins trois groupes hydroxy alcool pour atteindre un poids moleculaire desire.
