“…Variation in crystallization affects the processability, tensile, and impact properties of the blend. The addition of PP and compatibilizer affects the crystallization of PA6 . With the addition of compatibilizer, reduction in crystallization temperature and crystallinity was observed due to partial compatibility and increased interfacial adhesion .…”

PA6/polypropylene (PP) blends are investigated for obtaining balanced strength and toughness. The focus of this study is to understand the effect of PP content on mechanical property, water absorption, impact strength, thermal behavior, and morphology of PP in the absence and presence of PP‐g‐maleic anhydride compatibilizer. In comparison to pure PA6, all blends have higher impact strength with 161 and 124% increase at 5 wt % PP content in uncompatibilized and compatibilized blends (UB and CB), respectively. Morphology of impact fractured samples shows brittle fracture in the case of CB. scanning electron microscope of cryogenically fractured samples show decrease in domain size and change in shape from ellipsoid to spherical, from UB to CB. Then, 75% reduction in water absorption is observed for 50 wt % PP content UB. Postwater absorption yield strength (YS) remains constant above 10 wt % PP in both UB and CB and decrease in YS is less at higher PP content in CB. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

“…The results suggested that MCM-41 and SBA-15 exhibited favourable effect on flammability and tensile properties of PP nanocomposites. Lin et al (2013) studied β-PP/PA6 blends, and the results indicated that the addition of PP-g-MA resulted in PP-g-MA graft copolymer, which improved the interfacial adhesion and reduced the sizes of PA6 domains. Lee et al (2005) synthesized the PE/clay nanocomposites containing PP-g-MA by melt-intercalation method.…”

“…The heating rate and cooling rate were 10°C/min under nitrogen atmosphere. The crystallinity ( X c, DSC ) can be calculated with the following equation:

X_{c, DSC} = [Δ H_{normalm} / (w \cdot Δ H_{0})] * 100 %

where w is the mass fraction of each component; Δ H m is the melting enthalpy of the samples and Δ H 0 is the balance melting enthalpy, in this case, the melting enthalpy for 100% crystallizing MCPA is 230 J/g .…”

The monomer casting polyamide‐polyether amine (MCPA‐PEA) materials initiated by TDI‐PEA macroinitiator presented an obvious toughness characteristic which was contributed by the combination effect of PEA‐TDI macroinitiator and soft PEA component itself. The MCPA‐PEA materials with different content of PEA‐TDI macroinitiator or PEA component were prepared and then the respective contribution of PEA‐TDI macroinitiator and soft PEA component on the synthesis and performance were researched. It was found that the PEA‐TDI macroinitiator presented the dominant contribution and main influence on the polymerization process with higher activation energy and reaction order than PEA component. The PEA molecular chains did not participated in the crystallization process and made no influence on crystal structure of MCPA material whatever the way of copolymerization or blending. The PEA‐TDI macroinitiator also showed the dominant contribution on the decreasing effect of crystallization properties than PEA component with lower crystallinity and smaller spherulites size. The fibrous‐structure for MCPA‐0.3%PEA matrix was more obvious with notable deformation and high impact strength which further indicated the dominant contribution of PEA‐TDI macroinitiator on toughness. The toughening mechanism was deduced as the vast energy consumption by intense extension of fibrous‐structure and the highly orientation of molecular chains. POLYM. ENG.
