• Resumen

  • Here we report a simple and inexpensive experiment with propagating fronts of addition polymerization that demonstrates a method of testing the steady-state model of polymerization and includes the effects of heat losses and gravity on a chemical reaction. The experiment we describe involves a novel approach to polymeric materials synthesis but requires no more than test tubes, two inexpensive chemicals, a ruler, and a stopwatch.
