Abstract A simple procedure for the determination of the crystalline fraction in isotactic polypropylene, suitable for routine work, is described. It gives lower figures for the crystalline fraction than the method recommended by N ATTA , C ORRADINI , and C ESARI in 1957. The correctness of the results (within the limitations inherent to the concept of crystallinity in polymers) is supported by the consistency of the results with those obtained by the recently published very remarkable quite elaborate and sophisticated procedure of W. R ULAND .
