Abstract
A novel apparatus and method are provided for monitoring gas entrainment in liquid precursors for reaction injection molding (RIM). In accordance with the invention, a nucleated RIM precursor is sampled and the sample subjected to a controlled volumetric change. The measured pressure of the expanded or compressed sample is compared to that corresponding to the ideal degree of gas entrainment. The comparison is used to control the addition or withdrawal of entrained gas.
