Abstract
A method for rapid polymerization, curing or a combination thereof of a polymerizable or curable composition to yield polymers and composites based on these polymers through the utilization of short wavelength microwave energy is described. The inventive method is generally applicable to the chemical transformation of any organic material that can be processed by heating. This invention also relates to specially prepared particulate polymerization curing materials which, when dispersed and irradiated in a polymerizable or curable composition, will effect rapid polymerization, curing or a combination of polymerization and curing of that composition without exceeding the decomposition temperature of the polymerizable or curable composition when the composition is exposed to microwave radiation. The polymerization agent may also be encapsulated by a material which coats the polymerization agent to prevent its premature release into the polymerizable or curable composition.
