The process comprises steps of adding ingredients to the extruder at the feed zone, mixing the ingredients under heat to effectuate reaction between the ingredients to produce a liquid product exiting the extruder, and converting the liquid product exiting the extruder to the solid gel resin. A solid gel resin produced by the continuous process is also provided.
