Title

AN INVESTIGATION ON NON-ISOTHERMAL CRYSTALLIZATION BEHAVIOR AND MORPHOLOGY OF POLYAMIDE 6/ POLY (ETHYLENECO-1-BUTENE) -GRAFT-MALEIC ANHYDRIDE/ORGANOCLAY NANOCOMPOSITES

Abstract

 Nanocomposites based on POLYAMIDE 6 (PA6) and poly (ethylene-co-1-butene) -graft-maleic anhydride (EB- g -MAH) blends have been prepared via melt mixing. The effect of blend ratio and ORGANOCLAY concentration on the CRYSTALLIZATION and melting behavior of specimens were studied. Three types of commercial organo-modified clay (Cloisite 30B, Cloisite 15A and Cloisite 20A) were employed to assess the importance of the nanoclay polarity and gallery distance. The CRYSTALLIZATION behavior was investigated using differential scanning calorimetry (DSC) and wide angle X-ray diffraction spectroscopy (WAXD). The strong interactions between amine end groups of PA6 and maleic anhydride groups of EB-g-MAH led to complete inhibition of EB-g-MAH CRYSTALLIZATION according to the DSC results. A transformation from the α form to the γ form crystals of PA6, induced by both ORGANOCLAYs and EB-g-MAH, was monitored by WAXD and DSC. Small angle X-ray scattering (SAXS) was used to evaluate the MORPHOLOGY of nanocomposites. Moreover, transmission electron microscopy (TEM) was conducted to determine the location of ORGANOCLAYs and indicated that the ORGANOCLAYs mainly present in the PA6 matrix and rarely distribute in the EB-g-MAH phase in the case of low polarity ORGANOCLAYs. It was also evidenced that the ORGANOCLAY with the most affinity to PA6 (Cloisite 30B) had the largest effect on the thermal and CRYSTALLIZATION behavior of this phase in the blend.
