The effect of dilution (plasticization) of polymers on their mechanical         response is important for practical application such as in the                  manufacture of paints and adhesives.  If polymer produces a local               modification of solvent or base stock, it is possible that many                 applications of polymers are useful because the modifications of the            solvent itself are highly desirable.  One case in point is the role of          polymer additives used in lubricating oils; this may be a major factor          in the improved properties observed for polymer-loaded oils.  This              research will study the effect of diluation and solvent type on the             viscoelastic behavior of two linear amorphous polymers polystyrene and          poly (ethyl Ethylens).  Creep and creep recovery along the differential         scanning calorimetne and ahaltometric measurements will be made.  The           study will provide the data base for a variety of system parameters             used to develop theortical representation of the effect or polymer              solvent thermodynamies on the iscoelastic properties of polymers.
