摘要
The cocrystallization and phase segregation phenomena reported in the preceding paper of this issue have been reconfirmed by measuring the temperature dependence of the wide-angle (WAXS) and small-angle X-ray scatterings (SAXS) using synchrotron radiation for the blend systems of deuterated high-density polyethylene with hydrogenous polyethylene species having various branching contents. On the basis of the WAXS, SAXS, and small-angle light scattering data in addition to the Fourier transform infrared spectral data reported previously, a difference in the crystal structure, lamellar structure, and spherulite structure has been compared between the blend samples with various degrees of branching.
