“…1, CI PLA = 0 for 10 : 90 PA-6-PLA samples, a result that provides evidence for encapsulation of the PLA dispersed phase in the PA-6 matrix. The same morphology was observed in a wider interval: up to 40 or above 60% PLA [9,10]. In the range of PA-6-PLA compositions from 20 : 80 to 90 : 10, the interpenetration networks were observed in the blends.…”

“…Previously, attempts were made to produce such materials via blending of PLA with polyamide-6 (PA-6) [9][10][11] through the introduction of a compitibilizing copolymer into the blend [12,13] and via blending of PLA with PA-11 and PA-12 [14,15]. Nevertheless, there were no macromolecular reactions between PLA (Bioflex ® ) and PA-6 in [9,10]; that is, the reactive compatibilization did not start, as evidenced by the selective extraction.…”

“…Nevertheless, there were no macromolecular reactions between PLA (Bioflex ® ) and PA-6 in [9,10]; that is, the reactive compatibilization did not start, as evidenced by the selective extraction. The replacement of copolyester with pure PLA and the introduction of compatibilizers made it possible to achieve partial compatibility of the polymers [13].…”

Blends of polyamide-6 and polylactide are prepared via reactive compatibilization. Their phase morphologies and compositions are characterized by the methods of IR spectroscopy, optical and scanning electron microscopy, NMR, dynamic mechanical analysis, and continuous extraction in a boiling solvent. It is shown that the formation of hydrogen bonds between polylactide and polyamide-6 substantially improves the compatibility of components. A large proportion of a copolymer is formed as a result of interchain exchange between polyamide-6 and polylactide molecules. The results open new possibilities to produce commercially attractive biodegradable materials with high mechanical and thermophysical characteristics.

Novel blends were prepared from biobased poly(trimethylene terephthalate) (PTT) and poly(butylene adipate-coterephthalate) (PBAT) using a twin screw extrusion process as a function of different weight ratios. Thermal stability, mechanical, and interfacial properties of PTT/PBAT blends were investigated using a thermogravimetric analyzer and mechanical analyzer. Phase behavior and surface morphology of the blends were characterized using scanning electron microscopy. Interfacial bonding value of the PTT/PBAT blend was evaluated from the Pukanszky empirical relationship. Viscoelastic properties of PTT/PBAT blends were investigated using the dynamic mechanical analyzer. PTT/PBAT blend exhibited higher thermal stability than the neat PTT matrix. The entire blend showed better interfacial adhesion between the matrixes. Storage and loss modulus of the PTT/PBAT blend reduces with increasing PBAT content. PTT/PBAT blend exhibited higher impact energy than the neat PTT matrix, because of its flexible and amorphous nature of PBAT polymer and increasing toughness.

“…The final properties of the polymer blends depend on the properties of their components, the composition and especially the compatibility of polymers; for most polymer blends is caused by specific interactions [11] , such as dipole-dipole, ion-dipole and hydrogen bonding interactions [12] . In some cases, due to the synergistic effect, the mixtures present better properties than their individual components [13][14][15] . In literature there are investigations involving the mixture of chitosan with different polymers [16] , such as poly(vinyl alcohol) [17] , poly(N-vinyl pyrrolidone) [18] , poly(ethylene oxide) [19] , cellulose [20] and its derivatives [21] , among others; however, there are no reports describing a polymer blend containing chitosan and poly(methylmethacrylate-co-butyl methacrylate).…”

Chitosan/poly(methyl methacrylate-co-butyl methacrylate) (PMMA-co-BMA) blends were prepared via a solution blending method in the presence of formic acid. The compatibility of the bioblends was studied by different methods, such as Fourier transform infrared and Raman spectroscopy, micro-Raman imaging, thermogravimetric analyses, differential scanning calorimetry and scanning electron microscopic analysis. According to the obtained results, it has been concluded that the PMMA-co-BMA/chitosan bioblends are compatible in all the studied compositions. Specific interactions between carbonyl and methyl groups of the PMMAco-BMA structure and methyl, amine and amide groups of chitosan are responsible for the observed compatibility. INTRODUCTIONConcerns about environmental problems such as global warming, pollution of natural resources, renewable energy use and cost of synthetic polymers have motivated an intense research of sustainable polymer systems where at least one component is biodegradable or biobased [1] . The commercial importance of polymers also have increased the need of discover of new materials with specific properties and applications; for this purpose new polymers have been synthesized and chemical modifications in conventional polymers have also been proposed, but these methods are more complicated [2,3] . However, the mixture of two or more polymers, giving rise to a polymer blend, seems to be an economical method to obtain new polymeric materials with desirable properties, without the need of synthesizes specialized polymer systems [4,5] .
