“…The most, popular aromatic isocyanates are (Table ) 4,4′‐diphenylmethane diisocyanate (MDI) ⁠ 2,4‐toluene diisocyanate or 2,6‐toluene diisocyanate (TDI) ⁠1,4‐phenylene diisocyanate (pPDI) . The aliphatic diisocyanates are also used and the most popular are 1,6‐ hexamethylene diisocyanate (HDI), isophorone diisocyanate (IPDI), 4,4′‐ methylenebis(cyclohexyl isocyanate) (HMDI) . Diisocyanate used can be divided into several groups: aliphatic and aromatic or symmetric such as pPDI, HDI, and CHDI and asymmetric such as HMDI, TDI, and MDI.…”

“…In the case of the aliphatic diisocyanates as HDI, IPDI, or HMDI, this problem is not observed. There are also special purpose diisocyanates as 1,5‐ naphthalene diisocyanate (NDI), which is used to produce elastomers that are exposed to high temperatures and must maintain excellent mechanical and load‐bearing properties . As aforementioned, kind of used diisocyanate has a great importance for the properties of the obtained materials.…”

Thermoplastic polyurethanes (TPUs) materials are obtained by the reaction of polyol (ether-, ester-, and carbonate-based diols with average molecular weight in the range from 1,000 to 3,000 g/mol) with aliphatic or aromatic diisocyanates. Synthesized materials consist of the hard and soft segments which are separated in different level. All mechanical and thermal properties of TPUs depend on the chemical structure of used monomers, volume fraction, and interaction between the hard and soft segments. Presented work is the review of the synthesis and the structure-properties relationship analysis in the case of TPU. The most popular reactants used for the production of the TPUs have petrochemical-based origin.

“…On this topic, a great number of studies have been done, incorporating the ground tire rubber (GTR) into thermoplastics, thermosets, and rubbers . Recently in thermoplastics, GTR has been added to polypropylene (PP), low‐density polyethylene, high‐density polyethylene (HDPE), poly(vinyl chloride), and others . Usually the addition of GTR in polymers causes a degradation of their mechanical properties.…”

Ground tire rubber (GTR) was modified by sulfuric acid in order to improve its compatibility with and reinforcement of a polypropylene (PP) matrix. Polymer composites PP/GTR were prepared by melt mixing at different concentrations, with a maximum of 50 wt % of GTR. Studies by Fourier transform infrared spectroscopy (FTIR), surface specific area by BET (Brunauer, Emmett, and Teller), and scanning electron microscopy were used to characterize the untreated GTR and treated GTR, while the mechanical and thermal properties of the PP/GTR composites were assessed to understand how the surface treatment of GTR affected the mechanical and thermal properties of the composite PP/GTR. FTIR revealed the presence of sulfonic groups on the surface of sulfuric acid–treated GTR, and BET analyses showed an increase of about 625% in the specific surface area as a result of the high porosity produced by the treatment. In all composites containing treated GTR, a higher Young's modulus was obtained than for composites containing untreated GTR. Particularly, an increase of about 275% in the Young's modulus was obtained in composites with treated GTR (40 wt %) against that containing untreated GTR. However, a more significant reduction of the elongation at break was observed in composites containing treated GTR than in those containing untreated GTR. Also, an increase of the crystallization temperature of PP as a function of GTR was observed by differential scanning calorimetry, but the crystallinity of the composites was reduced by the addition of both untreated and treated GTR. © 2017 Wiley Periodicals, Inc.

“…The intensive bands at 1450 and 1377 cm −1 that appeared in the spectra of the pure glycerolysate, naphthenic oil, natural rubber, and composites, are attributed to deformation vibrations of methylene groups -CH 2 [33]. The most intensive peak for glycerolysate at 1096 cm −1 and peak for lignin spectrum at 1030 cm −1 are connected with the stretching vibration -C-O ether groups and with the deformation vibrations of -C-O methoxyl groups, respectively.…”
