There are wide discrepancies in the literature values for the heat of fusion (ΔHu) of isotactic polypropylene. A study was therefore made of the variables affecting ΔHu as determined by differential thermal analysis. The results of this study show

An average fiber axis orientation in polypropylene film was measured quantitatively from x‐ray diffraction determination of orientation of two planes containing this axis. This orientation was expressed as the average square cosine of the angle bet

The polymerization of bis(β-chloroethyl) vinylphosphonate to a crystalline solid was carried out with a Ziegler-Natta catalyst. A confirmation of the crystalline nature of the polymers was carried out by x-ray diffraction. The polymers would not mel

For polyethylene fibers, orientation parameters of the form 〈cos2 ϕ〉 were calculated from traces obtained with an x-ray diffractometer equipped with an orientation integrator. The angle ϕ is that which a crystal or molecular axis makes with the

Solid solutions of AlCl3 and TiCl3 were formed in all proportions by milling together dry powders of AlCl3 and TiCl3 (delta crystalline modification). For each composition, X-ray diffraction showed a single phase having a high degree of layer stackin
