Synthesis and Characterization of Poly (Polyethylene Glycol Anhydride) (PPEGA) Copolymers with Use of Different Catalysts for Application to Food Packaging as Polymeric Phase Change Materials (PCMs)
Author(s): Tugba Gungor Ertugral*
In this study, Poly (Polyethylene Glycol Anhydride) (PPEGA) copolymers synthesised with Maleic Anhydride (MA)
and Poly(Ethylene Glycol) (PEG) using two different catalysor; para toluene sulfonic acid and 1,8-Diazabicyclo [5.4.0]
undec-7-ene as polymeric SSPCM. PPEGA block copolymers were Solid-Solid Phase Change Materials (SSPCMs) as
new Phase Change Material (PCM). The PEG bound to the side chains of the copolymers stored latent heat as it
passed from crystal phase to the amorphous phase. Characterization and thermal specifications of SSPCMs were
determined by Fourier Transform Infrared (FT-IR) and Differential Scanning Calorimetry (DSC). DSC results
showed a SSPCM transition at 36°C-54°C temperature range and 163 Jg-1-153 Jg-1 enthalpy. All findings indicated
that the prepared PPEGA copolymer good Thermal Energy Storage (TES)... View More»
