Title Polypropylene/poly(trimethylene terephthalate) blend nanocomposite: a thermal properties study
Date 09.05.2012
Number 30304
Abstract In this article, thermal properties of polypropylene/poly(trimethylene terephthalate) melt-mixed blends containing organically modified montmorillonite nanoclays and interacting compatibilizers are studied. Dynamic mechanical analysis showed an enhanced elastic modulus and reduced damping upon nanoclay fillers incorporation, also a-relaxation peak was shifted up while ß-relaxation was not affected. Thermogravimetry exhibited a synergistic effect in thermal stability of the blend accompanied by a reduction in decomposition rate. This effect was more pronounced in presence of compatibilizers. The addition of nanoclay fillers generally led to an enhancement of thermal resistance; however, a dual function was evident, namely preventive and catalytic, respectively prior to and after onset of degradation.
