Notizen:
Information is presented on those physical properties where measurement is greatly facilitated by thermal stability greater than previously known in polyoxymethylenes, and properties of a mechanical nature characteristic of high molecular weight polymeric materials. The high molecular weight polyoxymethylenes studied possess the characteristic properties of a semicrystalline material in the high molecular weight range. The melting point, stiffness, and tensile strength of these materials substantially exceed those for linear polyethylene, which suggests that the effective chain interactions are enhanced by ease of close packing of the chains. High density and high crystallinity are in accord with this picture.
