Estimation of the molecular weight and other parameters of macromolecules in jute by low-angle X-ray methods

Summary Low-angle X-ray scattering methods have been applied to determine the molecular volume and the molecular weight of the macromolecules present in jute fibres. The well-known low-angle scattering camera ofKratky (1) was used and the angular range investigated is from 0.17×10^–3 to 3.0×10^–3 radians. The evaluation of the parameters and the quantities were made after the theories ofGuinier (2),Kratky (3), andPorod (4).The particles in jute fibres may be of the lamella type as pointed out byKratky (30) and also recently byRoy andDas (33). The molecular volume of the macromolecules is found out to be 9.995 × 10⁶ ų . The molecular weight is 7.703×10⁶.With 5 figures and 1 table
