Volume 14, Issue 2 , 2017, , Pages 3-16

  In this research samples of PVOH were synthesized at various reaction conditions (temperature, time, and amount of catalyst). First at 25˚C and 45˚C and constant catalyst weight samples of PVOH were prepared with different degree of hydrolysis at various times. For investigation of the effects of temperature, ...  Read More

Response Surface Methodology for Investigating the Effects of Hydrolysis Reaction Parameters on Molecular Structure and Performance of Polyvinyl Alcohol as Primary Suspending Agent

Z. Alihemati; A.H Navarchian

Volume 14, Issue 1 , March 2017, , Pages 52-66

  This study presents the synthesis of polyvinyl acetate (PVAc) by solution polymerization and its partial hydrolysis to polyvinyl alcohol (PVA) using alkaline alcoholysis. The influence of the molar ratio of hydrolysis catalyst (NaOH) to PVAc and the time and temperature of the saponification reaction ...  Read More

Theoretical and Experimental Study of Falling- Cylinder Rheometer
Volume 1, Issue 2 , July 2004, , Pages 19-27

  The present study attempted deriving and solving the falling- cylinder governing equations for power law model non-Newtonian fluids. Based on this theoretical study, a novel falling- cylinder rheometer (FCR) was designed and constructed to measure the Theological properties of non-Newtonian fluids. Different ...  Read More
