Abstract

The trioxane copolymers with ethylene oxide are prepared in an inert organic solvent (I) using a catalyst in the presence of ethylene or propylene carbonate in proportion 0.005-0.05 mol/mol trioxane. The solvent may be a cycloalkane. They are used for mechanical, automobile, precision instrument and textile construction. Use of II improves the yield of product, its quality and provides a simpler process than known methods which involve recycling trioxane.
