Structural, thermal and morphological characterization of functionalized macroporous copolymers

Abstract

Macroporous copolymers of glycidyl methacrylate and ethylene glycol di-methacrylate were functionalized with hexamethylene diamine, 1,3-bis (3-aminopropyl) tetramethyldisiloxane and α,ω-diamino propyl poly(dimethylsiloxane). The samples were characterized by Fourier transform infrared spectroscopy (ATR-FTIR), mercury porosimetry, scanning electron microscopy (SEM) with energy dispersive X-ray analysis (EDX), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Fuctionalization significantly alters porosity parameters, mechanism of thermal degradation and increases thermal stability. The sample functionalized with disiloxane exhibited better thermal stability comparing with the initial and other functionalized samples.
