Abstract
An automatic viscometer and sampling system suitable for monitoring changes in the molecular weight of polymers in solution is described. Automation provides significant increases in precision and accuracy. The instrument can be used to follow degradation or polymerization reactions induced by radiation, heat, or chemical reaction. Examples are given of its application to the study of photolytic and chemical degradation of polymers.Keywords
