Abstract
A dried gel (xerogel) prepared from ultrahigh molecular weight polyethylene was characterized using X-ray and low-frequency Raman scattering techniques, which evidence the presence of stacked lamellar crystals in the material. The architecture of these entities is similar to a sequence of alternating crystalline and amorphous regions in oriented semicrystalline polymers but in the case of isotropic material the stacks exhibit equal “long periods” in meridional and equatorial directions. The stack-like nature of crystalline entanglements in the gel network is concluded.
