Abstract:
An improved process for preparing polyformals is provided which comprises condensing an aliphatic diol, in which the hydroxyl groups are separated by at least four carbon atoms, with an essentially stoichiometric amount of formaldehyde in the presence of a Bronsted acid catalyst and contacting the condensation product with an organic epoxide in an amount sufficient to react with the residue of said catalyst.
