Abstract
Process for the preparation of high molecular weight copolymers, characterized by polymerizing a solution or dispersion of trioxane and a polyformamide of the general formula - [- O - A - (O CH2)m -J]- where A represents an aliphatic, saturated or olefinic, straight-chain or branched hydrocarbon radical -eventually with aliphatic side chain containing one or more halogen atoms- or a cycloaliphatic or aralkyl radical, and m represents an integer comprised between 1 and and 20, by a single or repeated cooling at a temperature that corresponds at least to that of the phase transition between the liquid state and the solid state.
