X-RAY CRYSTALLINITY DETERMINATIONS ON THE SYNDIOTACTIC 1,2-POLYBUTADIENE
X-射线法测定间规-1,2聚丁二烯结晶度

Using the atomic scattering factors approximation expression and computer, the atomic scattering factors were calculated. Then the correct factors for fotar main crystal planes of the syndioitactic 1,2-PBD were calculated. The correct factors were clearly defined. X-ray crystallinity formula was found.
