Abstract

Semiconducting behavior and thermokinetic study of terpolymeric resin-I derived from p-hydroxybenzaldehyde, adipic acid and ethylene glycol

Author(s): Amit N. Gupta, Vinay V. Hiwase, Ashok B. Kalambe

Resin abbreviated as HBAE-I was synthesized by polycondensation in presence of PPA using phydroxybenzaldehyde (0.1M), adipic acid (0.1M) and ethylene glycol (0.3M). The structure of resin was assigned by elemental analysis, IR, NMR spectroscopy. Resin was found to show semiconducting behavior in the temperature range 302 K to 488 K. The activation energy of conduction was found to be 785.10 J mol-1. The thermokinetic parameters were determined by Freeman-Carroll (FC) and Sharp Wentworth (SW) method in temperature range 265- 6850C. The thermokinetic parameters calculated with aid of these methods were found to be in good agreement.
