Notes:
Polymer-polymer blends offer a route for enhancement of various properties. When immiscible polymers are blended together (in the presence of a compatibilizer), the blend properties are dependent on the morphology of the phases. Uniform, fine dispersions generally result in “average” properties. Discussed here are blends of polyamides or polyesters with polyolefins, particularly polyethylene, where small amounts (3-20 percent) of the former polymers dispersed as essentially parallel, thin, large laminae produce substantial reduction (3-100 times) of permeability properties in blow-molded/extruded articles. Physical properties of such blends, their permeability properties, and morphologies are discussed.
