Viscometric Study of Carboxymethyl Epoxy resin based polyesters

R. K. Patel, S. V. Patel

Abstract :

Various Epoxy resin based polyesters were prepared by reported method. The carboxymethylation of this polyester was claimed out by their reaction with mono chloro acetic acid. The resultant carboxymethylated polyesters (CMPEs) were characterized. The viscosity measurement of solutions of all CMPE was calmed out in DMF at 35+ 0.1oC. The ubbelohde suspended type viscometer was used for such measurement. The viscosity data of the solution of CMPE resins signified that the decrease in concentration of solution increases reduced viscosity (?red). This suggests the CMEF resins act as polyelectrolyte of anionic type. Thus the viscosity of the solution in DMF suppressed by adding water and KBr in DMF. Thus the viscosity measurements of solution of CMPE resins in DMF–Water–KBr (80:20:1%) gives the intrinsic viscosity. Also applying empirical equation is able to represent the viscometric data for all the resins. It may be stated that as the equation is quite empirical
