Abstract

a. Procédé de préparation du polyoxyméthylène en présence d'un catalyseur à base d'un composé d'organoaluminium fixé sur un amide d'acide carboxylique supérieur. b. L'amide d'acide carboxylique supérieur répond à la formule R**18-CO NH2 dans laquelle R**18 représente un groupe alkyle en C11 -C30 , ou à la formule R**19-CO NH-R**20-NH CO R**21, dans laquelle R**19 et R**21 représentent respectivement un groupe alkyle en C11 -C30 et R**20 représente un groupe alkyène en C1 -C10 ou un groupe divalent aromatique en C6 -C20 ou un groupe divalent alicyclique en C3 -C20. c.
