摘要

<正> By means of the intensity theory of X-ray scattering and the two-phase concept of high polymer

the basic formula of the crystaUinity in block copolymers has been proposed after the corrections of atomic

temperature

absorption

Lorentz and polarization factor. Application of this method to different type poly （oxyethylene-styrene）block copolymers and the same type block copolymers with different EO contents indicates that the crystallinity in poly （oxyethylene-styrene ） block copolymers increases with the increase of the EO content and decreases in the order: PEO-PS-PEO>PEO-PS>PS-PEO-PS.
