Synthesis, Characterization and Viscometric Study of Carboxymethyl Epoxy resin based polyesters

R. K. Patel, S. V. Patel

Abstract :

Viscometric study of solutions of various carboxymethylated epoxy resin based polyesters in 1,4–dioxane solvent was carried out. Measurement was performed using ubbelohde suspended type viscometer. The viscosity for all CMPE solutions were determined in 1,4–dioxane at 30+ 0.1oC. The viscosity data of all solutions suggest the decrease in concentration of solution which increases reduced viscosity (?red). Therefore the CMEF resins act as polyelectrolyte of anionic type. The viscosity of the solution in 1,4–dioxane suppressed by adding water and KBr, though the intrinsic viscosity measurements are carried out for all resin solutions in Dioxane–Water–KBr having 75:25:1% ratio. Also empirical equation was adept to represent the viscometric data for all the resins. It may be stated that as the equation is quite empirical.
