## Abstract The influence of the acidity of organoaluminum compounds and their complexes on the catalytic activity in polymerization of trioxane has been studied. It is found that the catalytic activity of organoaluminum compounds of the type __R__~__n__~ALX~3βˆ’__n__~ depends on __n__ as well as the
