Title

SYNTHESIS, THERMAL AND ELECTRICAL PROPERTIES OF COPOLYMERS BASED ON 4,4’-BIPHENOL

Abstract

A series of copolymer resins (4,4’-BP-TETA-F) have been synthesized by condensation polymerization of 4,4’-biphenol and triethylenetetramine with formaldehyde in presence of base catalyst. Thermal analysis was carried out in air atmosphere at the heating rates of 10 0C/min for studying its thermal degradation behavior and kinetics. Thermal degradation curve depicts three stages of decomposition and has been discussed with minute details by applying Freeman-Carroll, Sharp-Wentworth and Coat-Redfern equations to evaluate the kinetic parameters i.e., activation energy (Ea), order of reaction (n) and frequency factor (z). The data from Freeman-Carroll method has been used to determine various thermodynamic parameters i.e., entropy change (ΔS), free energy change (ΔF) and apparent entropy (S*). The electrical property of 4,4’-BP-TETA-F copolymer resin was measured over a wide range of temperature (313 – 423 K). Electrical conductivity of the copolymer resin was found to be in the range of 8.8457 x 10-23 to 6.7959 x 10-23 ohm-1 cm-1.
