Renewable thermoplastic blends based on polyurethane (TPU) and polyamide (DAPA) obtained from dimers of fatty acids were reinforced with mineral microfillers, surface coated calcium carbonate (CaCO 3 ) or high aspect ratio talc (HAR), to prepare different micro-biocomposites systems. The influence of the nature of the filler, the aspect ratio and the filler content (5, 10, and 15 wt %), for different TPU/DAPA ratios (20/80, 50/50, and 80/20 wt %/wt %), were specifically investigated. Differential scanning calorimetry (DSC) and thermogravimetric analyses were conducted to investigate the thermal properties. DSC analyses showed that the addition of CaCO 3 had no influence on the glass transition and the melting temperature of the corresponding composites. Moreover, the morphology and the mechanical properties in the solid state of the different multiphase systems were investigated. SEM observations after tensile tests showed that the best matrix/filler interactions were obtained in the case of the 20/80-based systems. Uniaxial tensile tests have shown that the addition of HAR or CaCO 3 fillers led to a clear increase of the Young modulus. Micromechanical models based on a two-phase composite approach, including Mori-Tanaka and Davies models were used to describe the dependence of the elastic modulus on the volume fraction of HAR or CaCO 3 fillers.

P(N-phenylmaleimide-alt-styrene) (PNS) was synthesized, and nylon 6 (PA6)/PNS blends were prepared by melt blending. The heat resistant and crystallographic properties of PA6/PNS blends with different contents were investigated and analyzed. The results showed that the heat deflection temperature (HDT), relative crystallinity (X n ), and dynamic viscosity (η) increased with increasing PNS. The results of differential scanning calorimetry proved that PNS had played a positive role in nucleating PA6. Scanning electron microscosopy showed that the PNS domains were between 0.2 and 4 μm in diameter. The experimental results indicated that the addition of PNS improved the rigidity of PA6/PNS blends, thereby improving the heat-resistant properties of these blends.

In this work, nylon 6/ P(N-phenylmaleimide-alt-styrene) blends were prepared by melt blending, and the mechanical, heat-resistant, crystallographic and dynamical mechanical properties of nylon 6/ P(N-phenylmaleimide-alt-styrene) blends with different contents were investigated and analyzed. The results showed that the mechanical properties decreased with increasing PNS, while the heat deflection temperature (HDT), relative crystallinity (Xn), and storage modulus (G') increased with increasing PNS. The results of differential Scanning Calorimetry (DSC) proved the PNS played the positive role of nucleating PA6. And the results of dynamic mechanical analysis (DMA) proved the PNS could improve the rigidity of PA6/PNS blends. From the SEM, these PNS domains were between 0.2 and 4 μm in diameter. The experimental results indicated that the addition of PNS improved the rigidity of PA6/PNS blends, and then improved the heat-resistant property.
