The objective of the current paper was to define a rheological method for the study of the solvent/binder affinity. The adopted strategy involves the study of the intrinsic viscosity [η] of polymer solutions. [η] was estimated via an extrapolation procedure using the Huggins and Kramer equations. The effects of chemical structure and molecular weight on the polymer/solvent affinity were investigated.
Rheological properties of Ethyl Cellulose (EC), Polyvinyl Butyral (PVB) and Polyvinyl Acetal (PVAc) resins in a solution of a high boiling point glycol ether solvent were explored and compared. The intrinsic viscosity and the Mark-Houwink shape parameter were estimated for the three polymers and used as criteria for estimating the polymer/solvent affinity.
