Functionalization of Partially Bio-Based Poly(Ethylene Terephthalate) by Blending with Fully Bio-Based Poly(Amide) 10,10 and a Glycidyl Methacrylate-Based Compatibilizer

Abstract: This work shows the potential of binary blends composed of partially bio-based poly(ethyelene terephthalate) (bioPET) and fully bio-based poly(amide) 10,10 (bioPA1010). These blends are manufactured by extrusion and subsequent injection moulding and characterized in terms of mechanical, thermal and thermomechanical properties. To overcome or minimize the immiscibility, a glycidyl methacrylate copolymer, namely poly(styrene-ran-glycidyl methacrylate) (PS-GMA; Xibond™ 920) was used. The addition of 30 wt % bioPA… Show more

“…These additives are generally based on polymers with low molecular weight (Mw), oligomers, or even, more recently, functionalized vegetable oils with several reactive groups that are prone to form chemical bonds during melt processing [48,49]. In this sense, some commercially available copolymers and oligomers based on epoxy, maleic, or glycidyl methacrylate groups have successfully compatibilized biopolyesters and their green composites with lignocellulosic particles [22,[50][51][52]. The present study evaluated and compared the effect of surface treatments and different reactive compatibilizers on the performance of green composites based on PLA and short FFs prepared by twin-screw extrusion (TSE) and injection molding.…”

“…The three tested compatibilizers were added as different parts per hundred resin (phr) of composite. Particularly, PS-co-GMA and ESAO were both added at 1 phr, as this content has reported to enhance the interaction between biopolymers without leading undesired effects such as gel formation [50,59]. The selected MLO content was 5 phr since higher oil loadings could exert a negative effect by saturation [60].…”

“…In contrast, biobased polymers with the same chemical structures as conventional polymers, such as bioPE, bioPP, and bioPET, also share the same mechanical and thermal behaviours. These biopolymers differ in the origin of the components out of which they are synthesised, as they come from renewable sources instead of oil [ 1 , 4 , 9 , 10 , 11 , 12 ].…”

“…BioPE is a polymer that is synthesized from ethylene monomer derived from the dehydration of bioethanol obtained from the glucose of different biological raw materials such as sugar cane, sugar beet, corn or wheat starch, and lignocellulosic materials (Tsiropoulos et al, 2015). This material can reach up to 95% biobased content, which makes it more environmentally friendly than petroleum-based polyethylene (Jorda et al, 2019). Furthermore, CO 2 emissions from petrochemical PE are estimated to be 2.1 tonnes per tonne of polymer whereas for BioPE the emissions are -2.5 tonnes of CO 2 , indicating that it binds carbon, thus reducing CO 2 emissions to the atmosphere and the environmental impact compared to its petroleum-based counterpart (Garcia-Garcia, Carbonell-Verdu, Jordá-Vilaplana, Balart, & Garcia-Sanoguera, 2016;Samper-Madrigal, Fenollar, Dominici, Balart, & Kenny, 2015).…”
