“…PP/PAs blends, unfortunately, are immiscible and incompatible through the whole composition range due to their polar/nonpolar character, giving rise to unviable materials for practical use. For this reason, reactive compatibilization, for instance, has been widely used in these blends, where compatibilizing agents such as maleic anhydride (MA), 3,6,10,[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] acrylic acid (AA), 6,24,29,[31][32][33][34] or glycidyl methacrylate (GMA) 26,[35][36][37] linked to the PP have been used. These groups are able to react with the terminal amine groups in the PA, producing a graft copolymer which locates at the interface.…”

Compatible polymer blends of polypropylene (PP) with an amorphous polyamide (aPA) were obtained through reactive compatibilization by adding 20% maleic anhydride-modified copolymer (PP-g-MA) to the blends. The blends were made up of a pure PP phase and an aPA-rich phase where very small amounts of PP were detected. The dispersed phase particle size decreased considerably indicating that compatibilization occurred. Young's modulus of the compatibilized blends increased with respect to that of the uncompatibilized ones. The compatibilized blends were highly ductile, and the impact strength also improved, proving that compatibilization occurred under a broad range of experimental conditions.

“…Rengarajan et al [31][32][33][34] lucubrated solidphase graft copolymerization in 1990s. Recently, some researchers have developed the multi-monomers graft copolymerization [35][36][37][38][39][40][41][42][43][44][45] , which have higher graft degree than single-monomer graft copolymerization. Among them, Jia [42][43][44][45] has developed the ternary graft copolymers (PPTM), which has high graft degree, long graft chains, and adjustable length and polarity of side chains.…”

The ternary graft copolymers were synthesized by solid-phase grafting maleic anhydride (MAH), methyl methacrylate (MMA), and butyl acrylate (BA) onto polypropylene (PP), and applied in the interfacial modification of the PP/Calcium carbonate (CaCO 3 ) composites. Fourier transform infrared (FTIR) spectroscopy was used to analyze the structure of the ternary graft copolymers. Scanning electron microscopy (SEM), thermogravimetry (TG), differential scanning calorimetry (DSC), and dynamic rheological testing were used to investigate the morphology and the properties of the composites. FTIR results confirmed the occurrence of the solidphase graft copolymerization, and SEM exhibited the improvement of the compatibility between PP and CaCO 3 by PPTM. The properties testing showed that PPTM significantly contributed to the reinforcement of the composites in terms of mechanical properties, thermal properties, and rheological properties by acting as interfacial modifiers and plasticizers. The preferable loadings of PPTM for the properties improvement of the PP/CaCO 3 composites were between 7 and 9 phr.

“…In the past decades, a blend of polypropylene (PP) with polyamide-6 (PA6) has been paid more attention [1][2][3][4][5]. PP is one of the most versatile common thermoplastic polymers, owing to its outstanding performance, including low cost and great chemical resistance, but its application is limited by its impact strength.…”

In order to investigate the effect of LiCl on the miscibility and crystallization behavior of polypropylene/ maleic anhydride-grafted polypropylene/polyamide-6 (PP/ PP-g-MAH/PA6) blends, a series of PP/PP-g-MAH/PA6 blends with different LiCl contents were prepared by using a twin-screw extruder. The phase morphology of blends, crystallization behavior, crystal forms and compatibilizing mechanism were investigated by scanning electron microscopy (SEM), fourier transform infrared spectroscopy (FTIR), differential scanning calorimeter (DSC) and X-ray diffraction analysis(XRD). The results showed a small amount of LiCl could improve the miscibility of PP/PP-g-MAH/PA6 blends due to its catalysis for the reactions of anhydride of maleic anhydride-grafted polypropylene (PP-g-MAH) with the amino end groups of polyamide 6 (PA6). However, the situation was just the opposite in the presence of more than 0.75 wt% of LiCl. In addition, the hydrophilicity of polypropylene (PP) was largely improved due to the introduction of hygroscopic PA6 and LiCl. The water contact angle of PP-PA 2.25 decreased from 103°to 65°compared with pure PP. Thus this study might provide a promising route to generate polymer membranes in the wastewater treatment field.
