Abstract
A process for the manufacture of trioxane homopolymers and copolymers by polymerization of trioxane and mixtures of trioxane and cyclic ethers at temperatures between -50º C and 100º C in the presence of 0.001 to 1% catalysts of cationic activity, optionally in the presence of solvents, characterized by that the polymerization is carried out with the addition of 0.001 to 5% by weight, based on the monomers, of at least one boric acid ester of the formula B (0R)3 wherein R = alkyl residues with 1 to 20 carbon atoms, cycloalkyl radicals with 5 to 6 carbon atoms and aryl radicals with 6 to 14 carbon atoms.
