    Notes: 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 ΔHu for 100% “crystalline” polypropylene to be 2400 cal./mole repeating unit with 2σ = 300. The entropy of fusion is 5.4 e.u./repeating unit (2σ = 0.3). Thermal history, potential errors in sample-sensor contact as well as uncertainties in x-ray analysis for per cent crystallinity are discussed.

    Description / Table of Contents: Kationisch hergestelltes, kristallines Poly-3-methylbuten-1 wurde untersucht. RÖNTGENspektren und Differentialthermoanalyse lassen auf das mögliche Vorhandensein dreier kristalliner Polymermodifikationen schließen. Die Infrarotspektren kristalliner und amorpher Proben wurden untersucht.
    Notes: Crystalline, cationically obtained poly(3-methylbutene-1) has been investigated. X-ray and differential thermal analysis indicates the possible existence of three crystalline polymer modifications. The infrared spectra of crystalline and amorphous samples have been investigated.
