Abstract: | Ascending frontal polymerization in a body with a moving boundary was accomplished experimentally. This process was shown to be a steady‐state process within a certain range of the parameters. Temperature profiles of the front were recorded. This new method gives an excellent opportunity to prepare functionally gradient materials because composition of a monomer feedstream can be varied in a programmable manner. Polymer samples with hyperbolic gradients of optical dye concentration were manufactured at ambient pressure and temperature. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 78: 2398–2404, 2000 |
