Investigation of Thermal Degradation Kinetics of Poly(Ɛ-caprolactone) Grafted onto PEMA-co-PHEMA

Year 2017, Volume: 17 Issue: 1, 73 - 85, 24.04.2017

Abstract

Poly(ethyl methacrylate)-co-poly(2-hydroxyethyl methacrylate), PEMA-co-PHEMA, which
containing 5% 2-hydroxyethyl methacrylate (HEMA) was synthesized by the free radical polymerization.
ɛ-caprolactone was grafted -OH side group of PEMA-co-PHEMA via ring opening polymerization
method. A newly synthesized PEMA-co-PHEMA-g-PCL which grafted onto PEMA-co-PHEMA were
characterized by experimental measurements such as FTIR, 1H NMR and TGA techniques. The reaction
mechanism of degradation process and the kinetic parameters of the polycaprolactone grafted onto
PEMA-co-PHEMA in nitrogen environment were investigated by thermogravimetric analysis (TGA) at
different heating rates. The evident activation energies of thermal degradation for polycaprolactone, as
defined by the Kissinger’s, Flynn–Wall–Ozawa and Tang methods, which does not necessary knowledge
of the reaction mechanism (RM), were 108.58, 113.88 and 108.35 kJ/mol, respectively. These values
were compared using different integral and differential methods. An analysis of the experimental
results proposed that the reaction mechanism was an R3 deceleration type in the conversion range (2-
40%) studied.
