ABSTRACT:
A method is provided by which thermally stable polyoxymethylene containing polymers are produced. These polymers are prepared by polymerizing trioxane or formaldehyde which has been first treated with micro-wave radiation. Trioxane or formaldehyde treated in this manner is then suitable for homopolymerization or copolymerization with any of the variety of comonomers known to copolymerize with these materials. The resultant polyoxymethylene containing polymers are of exceptional thermal stability without the necessity of added stabilizers.
