In the last few years the resin and polymer production methods have changed from small batch kettles to large several ton capacity reactors. Since this change, many attempts have been made to devise a simple but rapid and accurate method of tracing the size of the polymer particle through its processing cycle to completion of polymerization to a previously determined point. Up to this time resin manufacturers have not had a rapid, continuous and reliable test method for materials at processing temperature which have the properties of a variable, rapid and critical increase of polymerization, and which may go to an insoluble and infusible stage before an operator realizes the necessity of corrective measures.

Over a year ago when thought was first given to this subject and the overall field of automation, we were naïve enough to think that this was a relatively unexplored field. Now, one scarcely picks up a magazine, journal, or newspaper without encountering articles, dissertations, and predictions on this topic.
