“…To this end, the modification of aromatic polyesters to make them more sustainable and biodegradable is a challenging task that has been extensively pursued in recent years [ 5 , 6 ]. Aromatic polyesters like poly(ethylene terephthalate) (PET) [ 7 ] or poly(butylene terephthalate) (PBT) [ 8 ] are widely recounted as premium thermoplastic materials with excellent thermal, mechanical, and optical properties among others, but their degradation in natural environments is insignificant. While these high-performance materials have enabled transformative progress, most of them still involve petroleum-based chemicals as monomers, which have antagonistic impacts on the environment.…”

In this work, the feasibility of replacing petroleum-based poly(ethylene terephthalate) (PET) with fully bio-based copolyesters derived from dimethyl 2,5-thiophenedicarboxylate (DMTD), dimethyl 2,5-dimethoxyterephthalate (DMDMT), and polysaccharide-derived 1,6-hexanediol (HDO) was investigated. A systematic study of structure-property relationship revealed that the properties of these poly(thiophene–aromatic) copolyesters (PHS(20–90)) can be tailored by varying the ratio of diester monomers in the reaction, whereby an increase in DMTD content noticeably shortened the reaction time in the transesterification step due to its higher reactivity as compared with DMDMT. The copolyesters had weight-average molar masses (Mw) between 27,500 and 38,800 g/mol, and dispersity Đ of 2.0–2.5. The different polarity and stability of heterocyclic DMTD provided an efficient mean to tailor the crystallization ability of the copolyesters, which in turn affected the thermal and mechanical performance. The glass transition temperature (Tg) could be tuned from 70–100 °C, while the tensile strength was in a range of 23–80 MPa. The obtained results confirmed that the co-monomers were successfully inserted into the copolyester chains. As compared with commercial poly(ethylene terephthalate), the copolyesters displayed not only enhanced susceptibility to hydrolysis, but also appreciable biodegradability by lipases, with weight losses of up to 16% by weight after 28 weeks of incubation.

This paper studies and evaluates the mechanical properties of a blend of Polyethylene terephthalate (PET) and high-density polyethylene (HDPE). The HDPE/PET blends are prepared by injection molding PET into HDPE with a ratio of 0%, 10%, 20%, and 30%, respectively. After the injection molding, the samples are measured for tensile strength according to standard D638. As a result, the tensile values of HDPE/PET gradually decreased with the ratio of 0%, 10%, 20%, and 30% (PET) and 18.45, 17.31, 15.45, and 14.43 MPa, respectively. It was shown that the tensile strength of the HDPE/PET composite decreased gradually as the PET percentage increased because the penetration of PET in the HDPE structure increased the elastic modulus of the PET ratio, leading to a decrease in tensile strength. The packaging is known to be mostly blown from HDPE, which has many outstanding features. However, some disadvantages exist, such as low bending strength, low heat distortion temperature, low transparency, and, most importantly, packaging. The packaging blown from HDPE is unstable. This problem is a limited application of HDPE in the packaging industry. To improve the recycling of plastic packaging from HDPE, adding PET is the most effective way. PET plastic packaging is transparent, flexible, toxic, and difficult to recycle, so it can only be used once. Incorporating PET into HDPE will improve the transparency and mechanical properties of HDPE and reduce the cost of PET plastic, and reduce environmental pollution.

“…A number of semicrystalline polymer matrices, such as poly(butylene terephthalate) (PBT), when reinforced by clay, have demon-strated desirable characteristics for a variety of practical applications. Especially, their significant improvement in heat distortion temperature, impact strength, and modulus has gained industrial interest [20][21][22][23][24][25][26]. Because of its easy processability, good mechanical properties, excellent dimensional stability, high stiffness, and hardness, PBT has been a highly desirable engineering thermoplastic for injection molding.…”

In contrast to the traditional fillers, clay, in particular, natural smectite clay represents an environmentally significant alternative to improve the properties of polymers. Compared to con-ventional nanofillers, smectite clay can effectively enhance the physical and mechanical properties of polymer nanocomposites with a relatively small amount of addition (< 5 wt%). The present study focuses on investigating the reinforcing efficiency of different amounts (up to 5 wt%) of a natural Brazilian smectite clay on the mechanical and thermal properties of poly(butylene terephthalate) (PBT) nanocomposites. Natural Brazilian clay modified by addition of quaternary salt and sodium carbonate (MBClay) was infused into the PBT polymer by melt extrusion, using a twin-screw extruder. It was found that the best properties for PBT were obtained at 3.7 wt% of modified BClay. Tensile strength at break exhibited an increase of about 60 %, flexural strength increased by 24 % and flexural modulus increased by 17 %. In addition, an increase in the crystallinity percentage of PBT/BClay nanocomposite was confirmed by DSC and XRD analysis, and a gain of about 45 % in HDT was successfully achieved due to incorporation of 3.7 wt% of MBClay.
