Various material data for a n isotactic polypropylene were acquired for the simulation of the injection molding of this material. Viscosity as a function of shear rate and temperature was measured using a capillary rheometer at high shear rates and a cone-and-plate rheometer a t low shear rates. Hea
l[Tth polymer molding techniques, it is possible to fabricate nanostructures with a replication fideli~' o~ 25 nanometers. Both hot embossing and injection molding can be used, and cycle times of down to 4 sec can be achieved m a CD injection molding process. The resolution is far below the structur
