“…This disadvantage limits its use in related applications like production of carpets, automotive interior parts, geotextiles and so on . In order to achieve dyeable PP surfaces, various methods such as blending with polar group‐containing polymers, copolymerization, plasma surface treatment, use of pigment masterbatch and others have been reported in the literature. Another method is to introduce nanoparticles into the PP matrix …”

Synthesis and characterization of a novel toughener-compatibilizer for polypropylene (PP)-montmorillonite (MMT) nanocomposites were conducted to provide enhanced mechanical and thermal properties. Poly(ethylene oxide) (PEO) blocks were synthetically grafted onto maleic anhydride-grafted polystyrene-block-poly(ethylene/butylene)-block-polystyrene (SEBS-g-MA). Special attention was paid to emphasize the effect of PEO-grafted SEBS (SEBS-g-PEO) against SEBS-g-MA on morphology, static/dynamic mechanical properties and surface hydrophilicity of the resultant blends and nanocomposites. It was found that the silicate layers of neat MMT are well separated by PEO chains chemically bonded to nonpolar SEBS polymer without needing any organophilic modification of the clay as confirmed by X-ray diffraction and transmission electron microscopy analyses. From scanning electron microscopy analyses, elastomeric domains interacting with MMT layers via PEO sites were foundto be distributed in the PP matrix with higher number and smaller sizes than the corresponding blend. As a benefit of PEO grafting, SEBS-g-PEO-containing nanocomposite exhibited not only higher toughness/impact strength but also increased creep recovery, as compared to corresponding SEBS-g-MA-containing nanocomposite and neat PP. The damping parameter of the same nanocomposite was also found to be high in a broad range of temperatures as another advantage of the SEBS-g-PEO toughener-compatibilizer. The water contact angles of the blends and nanocomposites were found to be lower than that of neat hydrophobic PP which is desirable for finishing processes such as dyeing and coating.

sheets and wound healing dressings in medical hospitals in addition to soldiers uniforms. Also, PP fibers are dyed with disperse dyes for use in carpets, rugs, upholstery, swim and sport wear fabrics. Review of the different methods of dyeing polypropylene includes the following: I. Blending PP chips with other polymers II. Dyeing PP using superfacial carbon dioxide. III. Mass coloration with metallic additives and pigments IV. Modification PP fabrics with selected monomers by radio-grafting techniques V. Dyeing PP by other means Blending PP chips with other polymers PP based polymer fibers containing various quantity (5-20%) of poly trimethylene terphthalate (PTT) were melt spun to modify PP structure[1]. The structure behavior change of blended fibers was analyzed by different methods. The poly blend fibers had increased dyeability with increase in PTT content along with excellent color and light fastness properties.

“…PET polimeri özellikle paketleme endüstrilerinde içecek şişesi, yiyecek kabı olarak kullanılmaktadır. Ayrıca PET malzemesi birçok durumda yüksek mukavemet, Young modülü, atmosferik ve biyolojik ajanlara karşı yüksek dirence sahip olmasından dolayı tercih edilmektedir [6][7][8]. Özellikle endüstri uygulamalarında bu konu ile ilgili çalışmalar devam etmektedir.…”

“…Bunun nedeni uyumlaştırıcısız karışımları iki ayrı faz olarak gözükmesidir. Ayrık fazda büyük küresel damlacıklar gözükmekte ve belirgin bir yapışma oluşmadığı için istenen mekanik özelliklere ulaşılmasında problemler ortaya çıkmaktadır [7]. PP/PET karışımları üzerine yapılan çalışmalarda PET katkısının kullanılmasının sebebi PET'in geri dönüştürüm malzemesi olma özelliğinden kaynaklanmaktadır.…”

Highlights: Graphical/TabularAbstract  Measurement of mechanical properties of PP /PET blends  Improving mechanical properties  Morphological characteristics of PP /PET blends When the morphology and mechanical properties of PP / PET mixtures are examined, it is seen that there is a more homogenized structure in PP +%30PET sample in SEM images. In PP + %40 PET mixture, the transition from droplet to fibril form appears more clearly. In PP +%50 PET mixture, homogeneity started to deteriorate again and gaps started to form again in structure it was observed that Young's modulus reached 2653.79 MPa in PP +%40 PET sample, and an increase of about 210% compared to pure PP. Figure A. SEM images of PP / PET mixtures and Young modulus change Purpose: In this study, the dynamic-mechanical and spectroscopic properties of PP / PET polymer blends with different ratios have been investigated experimentally and the effect of PET additive on dynamic-mechanical and spectroscopic properties has been tried to be explained. Theory and Methods: In this study, tensile test of PP and PET blends were tested at a drawing speed of 25 mm/min and at different ambient temperatures. SEM analyzes were performed and DMA tests used to determine the viscoelastic properties of PP / PET mixtures were performed at a frequency of 1 Hz from 30°C to 120°C with a temperature increase of 2,00 ° C / min. For structure characterization of PP / PET mixtures, FTIR analyzes were performed between 4000-650 cm-1. It was compared with the characteristic peaks of pure materials to see the interactions of PP / PET blend films. Results: It is observed that mechanical properties reaches its maximum value for all temperatures at 40% PET. There is a structural phase transition and matrix structure changes in the PP + 50% PET sample. Because PET and PP ratios are equal For this reason, it was observed that Young's modulus values decreased in comparison to PP + 40% PET in this example.SEM images also support this view. Conclusion: In this study, the effect of PET additives on the mechanical properties of PP, instead of glass fiber, was investigated especially for plastic pipe manufacturing., and it was concluded that the best mechanical properties were PP + 40% PET
