Influence of cubic alpha-Fe2O3 particles on the thermal stability of poly(methyl methacrylate) synthesized by in situ bulk polymerization
Апстракт
Poly(methyl methacrylate)/alpha-Fe2O3 Composites were prepared by in situ bulk radical polymerization of methyl methacrylate in the presence of the cubic alpha-Fe2O3 particles using 2,2-azobisisobutyronitrile as initiator. The cubic a alpha-Fe2O3 particles were synthesized by forced hydrolysis of FeCl3 and characterized by X-ray diffraction analysis and transmission electron microscopy. The molar masses and molar mass distribution of synthesized PMMA samples were determined by gel permeation chromatography. The influence of alpha-Fe2O3 filler particles on the thermal properties of the PMMA matrix was investigated using thermogravimetry and differential scanning calorimetry. The molar mass and polydispersity of PMMA extracted from composite samples were not influenced by cubic alpha-Fe2O3 particles. The obtained composites have better thermal and thermooxiclative stability than pure PMMA. On the other hand, the values of the glass transition temperature of composite samples were identic...al to the glass transition temperature of pure PMMA. (c) 2008 Elsevier Ltd. All rights reserved.
