Computerization of Ruland's X-ray method for determination of the crystallinity in polymers

A general procedure for determination of the crystallinity in polymers from the X-ray diffraction pattern was developed by modifying the method described by Ruland [Acta Cryst. (1961), 14, 1180-1185] on two points. One of these modifications furthermore permits substantial reduction of the required number of experimental data without a serious loss of accuracy being involved.
