The equal channel angular extrusion (ECAE) process has been shown to be effective in altering the morphology, both at the micrometer and at molecular levels, in linear low-density polyethylene (LLDE). The ECAE process can effectively force the spherulitic structure in LLDPE system to undergo lamellae slip, rotation, fragmentation and orientation. The presence of the oriented lamellae structure will lead to improvements in strength, modulus and solvent resistance in LLDPE. It is conceivable that the ECAE process can shear orient liquid crystalline polymers, blends, nanocomposites, and filled systems. Optimized morphology and property in polymeric systems can be realized if the ECAE process is used.
