This work deals with the effect of compatibilizer on the morphological, thermal, rheological, and mechanical properties of polypropylene/polycarbonate (PP/ PC) blends. The blends, containing between 0 to 30 vol % of polycarbonate and a compatibilizer, were prepared by means of a twin-screw extruder. The compatibilizer was produced by grafting glycidyl methacrylate (GMA) onto polypropylene in the molten state. Blend morphologies were controlled by adding PP-g-GMA as compatibilizer during melt processing, thus changing dispersion and interfacial adhesion of the polycarbonate phase. With PP-g-GMA, volume fractions increased from 2.5 to 20, and much finer dispersions of discrete polycarbonate phase with average domain sizes decreased from 35 to 3 mm were obtained. The WAXD spectra showed that the crystal structure of neat PP was different from that in blends. The DSC results suggested that the degree of crystallization of PP in blends decreased as PC content and compatibilizer increased. The mechanical properties significantly changed after addition of PP-g-GMA.

“…Polypropylene (PP) and polyamide 6 (PA6) are two widely used polymers in automotive industries either as homopolymers or their blends. The inherent incompatibility of most polymers including PP and PA6 has interested many to find methods to optimize their melt blending process . The incorporation of different compatibilizing agents has been considered in a lot of works for many years .…”

The relaxation of carbon nanotube (CNT)‐filled PA6 droplets in PP matrix was studied after cessation of simple shear flows. The morphology evolutions of blends with various CNT contents in PA6 were probed by optical microcopy over time. It was shown that the retraction of deformed droplets accelerates with increasing CNT content in PA6. As evidenced by linear rheological measurements, gradual formation of elastic structures within the droplets was found responsible for such observations. The pre‐shearing flow was varied to investigate the effects of different flow histories on the kinetics of relaxation. By increasing the shear‐rate of the flow prior to relaxation, the relaxation kinetics slowed down to some extent. The slowed‐down kinetics was attributed to the partial rupture of the elastic structures within PA6. This idea was evidenced by performing the startup of steady shear flow experiments on PA6/CNT nanocomposites. The final morphology of the blends after the melt blending process was analyzed. The average droplet size was found to increase with increasing the CNT content. Also, the distribution of the droplet sizes became broader as a result of the increased viscosity and elasticity ratios. POLYM. ENG. SCI., 56:51–60, 2016. © 2015 Society of Plastics Engineers

“…Nylon 6 (NY6) resins are well known for their excellent toughness, wear, adhesion, high impact strength, fatigue resistance, and thermal stability, which contribute to them being widely used as textile and composite materials [1–9]. However, the tenacity values of NY6 fibers are still significantly lower than those of other high performance fibers, such as, ultra‐high molecular weight polyethylene and poly(ethylene terephthalate) fibers, that inhibits their usage in many other applications, such as, reinforced fibers in Geotextiles and tire cord fibers.…”

“…Several attempts have been made to improve the tenacity values of NY6 fibers over the last several decades [2–9]. The drawing and tensile properties of NY6 fibers have been improved efficiently after addition of proper crystallization inhibitors (e.g., carbolic acid [2], naphthalen dicarboxylic acid, isophthalic acid, diphenyl‐4,4′ dicarboxylic acid, and 4,4′‐diphenyl ether dicarboxylic acid [3]).…”

This study systematically investigated the drawing and ultimate tenacity properties of the Nylon 6 (NY6)/nylon 6 clay (NYC) composite fiber specimens prepared at varying NYC contents and drawing temperatures. The achievable draw ratio (Dra) values of NY6x(NYC)y as‐spun fiber specimens initially increase in conjunction with NYC content, and then approach a maximum value, as their NYC contents and drawing temperature approach the 0.5 wt% and 120°C, respectively. The percentage crystallinity (Xc) values of NY6x(NYC)y as‐spun fiber specimens increased significantly, as their NYC contents increased from 0 to 2 wt%. As revealed by high power wide angle X‐ray diffraction analysis, α form NY6 crystals grew at the expense of γ form NY6 crystals originally present in NY6x(NYC)y as‐spun fiber specimens as their draw ratios increased. The ultimate modulus, tenacity, and orientation factor values of NY6x(NYC)y fiber specimens approach a maximum value, as their NYC contents and drawing temperatures approach the 0.5 wt% and 120°C optimum values, respectively. The thermal and melt shear viscosity experiments were performed on NY6x(NYC)y resins and/or fiber specimens to determine the optimum NYC content and possible deformation mechanisms accounting for the interesting drawing, orientation, and ultimate tenacity properties found above.
