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.
