Abstract
The invention includes a method of increasing polymerization within a condensation polymer. A substantially dry condensation polymer material is provided. The material is exposed to radiation having a frequency less than microwave frequency for a time of at least about 0.5 hour to increase an amount of polymerization within the material. The invention also includes a method of treating a polyamide material. A polymeric polyamide material is provided and exposed to first radiation having a first power intensity. The material is then exposed to second radiation having a second power intensity. The first power intensity is higher than the second power intensity. Additionally, the invention includes an apparatus. The apparatus includes an inlet port through which a feed material enters the apparatus, and an outlet port through which the feed material passes out of the apparatus. The apparatus further includes a feed material flow path from the inlet port to the outlet port, The flow path comprises at least two radio-frequency radiation reaction zones which comprise different power intensities of radio-frequency radiation relative to one another. The invention further comprises methods and apparatuses utilized for treatment and/or formation of nylon.
