Abstract

The studies reported herein were designed to develop a better understanding of the influence of different crosslinking agents on the polymerization of acrylamide gel systems and upon the resulting physical properties of the composites. Specimens were developed via a gel-casting process for viscoelastic and diametral tensile strength testing and the chemical reactions were monitored by Raman spectroscopy and isothermal calorimetry. The studies have demonstrated the ability to tailor the properties of a gel-cast system over a relatively wide range of reaction rates and the resulting mechanical properties by utilizing small adjustments to the overall chemistry of the system.
