Abstract: Polymers and copolymers of trioxane are produced in substance by means of cationic catalysts at 60 DEG to 120 DEG C. by introducing the reaction components on to a flat chamber mould, having a small open surface, capable of being cooled externally and provided with a lining of an apolar plastics within a period which is shorter than the induction time of the polymerization, cooling the mould during the polymerization, and keeping the temperature of the mould above the melting point of the reaction components while the mould is being emptied. Cyclic ethers, cyclic acetals, cyclic ketals, cyclic esters, and polyacetals are specified comonomers, boron triflouride and its co-ordination complexes being preferred catalysts. Polyethylene, polypropylene and polytetrafluoroethylene are specified apolar plastics. Apparatus for carrying out the process is described.
