Abstract
Na-MMT intercalated with PEGMA macromer was prepared using an EtAc/acetone mixture (1/1 by volume) as a solvent. PEGMA/(Na-MMT)-co-MMA/MA nanocomposites was synthesized by copolymerizing intercalated compound with MMA and MA, and then characterization was performed. The results of X-ray diffraction (XRD) showed that in the case of Na-MMT intercalated with PEGMA macromer the d-spacings of silicate of Na-MMT increased with increasing of Na-MMT loading. As the Na-MMT loading increases Tg showed increasing trend through the DSC measurement. TGA result showed that thermal stability of PEGMA/(Na-MMT)-co-MMA/MA nanocomposites improved a little more than the pure PEGMA-co-MMA/MA.
