“…This phenomenon also occurred with PBF based copolymers; for instance, PBF-co-PBS copolyesters exhibited a crystalline structure when the content of butylene furandicarboxylate (BF) was lower than 20 mol% or higher than 70 mol% and nearly amorphous structure when the content of BF was between 30 and 60 mol%. 96,98 This same tendency was also observed for PBA-co-PBF copolyesters. 95,97 As expected, the thermal properties of the corresponding copolyesters were also affected by their crystalline structures (Table 2).…”

Biobased polyesters and other polymers from 2,5-furandicarboxylic acid: a tribute to furan excellency

Motivated by a general concern on sustainability and environmental issues, a sparkling search for renewable-based polymers has grown exponentially in recent years. This search definitely spotlighted polyesters derived from 2,5-furandicarboxylic acid, among other polymers, as some of the most promising, especially due to the resemblance of this renewable monomer to the well-known petroleum-based terephthalic acid, as well as for the possibility of preparing innovative materials. The huge number of recent papers and patents about this family of polymers explore aspects such diverse as synthesis with other renewable-based monomers, leading to the preparation of materials with enhanced thermo-mechanical, biodegradability and liquid crystalline properties, among other features. Additional aspects pursued in such studies are innovation in the synthetic approaches or its optimisation; and also the development of applications for everyday-life objects like for example packaging materials, especially bottles, textiles, coating, toners, among many other uses. Despite this intense activity little has been reviewed recently about this unique family of polyesters, or derived polymers, as the only reviews on the subject date-back from the last century. In this perspective, the present appraisal aims at contributing to fulfil this literature gap, covering recent aspects related with challenges of developing polyesters, polyamides, or other polymers from 2,5-furandicarboxylic acid and their precursors. Emphasis is placed on monomer synthesis, polymerisation reactions, catalysts and applications.A tribute to 2,5-furandicarboxylic acid excellency and the myriad of novel polyesters, but also polyamides, among other polycondensates, is comprehensively done.

“…The first such study described the synthesis and characterization of fully b i o b a s e d p o l y ( b u t y l e n e s u c c i n a t e -c o -b u t y l e n e furandicarboxylate)s, 31 followed by a similar approach for preparing poly(butylene adipate-co-butylene 2,5-furandicarboxylate)s, 32 in which the important issue of the purity of FDCA (often questioned and assumed to be the source of coloring in the ensuing polymers) was tackled with an original alternative purification process. These two copolymer families were shown to afford tunable properties as a function of the comonomer composition, ranging from crystalline polymers, possessing a good tensile modulus (360−1800 MPa) and strength (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35), to essentially amorphous polymers with a low T g and very high elongation at break (about 600%), useful as thermoplastics, elastomers, or impact modifiers. The copolyesterification system ethylene glycol/ FDCA/succinic acid was also studied, 33 and it showed that this material was a suitable alternative to poly(ethylene terephthalate-co-ethylene succinate) (PETS), a well-known PET copolymer.…”

“…15 Este copoliéster supera as desvantagens observadas em outros materiais alifáticos, pois combina boas propriedades mecânicas com biodegradabilidade. 16 O PBAT também oferece propriedades de barreira especiais como, por exemplo, alta permeabilidade ao vapor de água, o que predestina seu uso em embalagens de frutas e vegetais, nas quais ajuda a evitar o crescimento de fungos. Suas propriedades de barreira e, sobretudo, sua compostabilidade, devem ser levadas em consideração na determinação das suas possibilidades de uso, principalmente em aplicações onde é benéfico dispor de um plástico compostável, resistente ao rasgamento, à prova de água, resistente à perfuração, capaz de receber impressão e permeável ao vapor de água.…”

Abstract:The biodegradable polymers pass by a degradation process resulting from action of microorganisms such as bacteria, fungi and algae. These polymers are being used as matrix in the composites obtained with natural fibers seeking to improve the mechanical and thermal properties without amending the biodegradability characteristics of the product. Thus, this study evaluated the biodegradation of composites obtained from commercial blends of poly (butylene adipate-coterephthalic) (PBAT) and starch as matrix and rice husk (CA) using two different techniques. PBAT starch systems with 10, 20 and 30% RH were obtained in an internal mixer and evaluated by weight loss by biodegradation test in the simulated ground, using the Sturm test. The tests for weight loss indicates that the attack of microorganisms occurs preferentially in the matrix. However, the atmosphere used in the Sturm test to evaluate the degradation was favorable biodegradation of samples of rice husk.Keywords: Biodegradation; Composites; PBAT-starch; Rice husk. ResumoOs polímeros biodegradáveis passam por um processo de degradação resultante da ação de microorganismos tais como bactérias, fungos e algas. Estes polímeros estão sendo utilizados como matriz na obtenção de compósitos com fibras naturais buscando melhoria nas propriedades mecânicas e térmicas sem que altere as características de biodegradabilidade do produto. Sendo assim, este trabalho avaliou a biodegradação de compósitos obtidos com a blenda comercial de poli(butilenoadipato-co-tereftálico) (PBAT) e amido como matriz e a casca de arroz (CA) utilizando duas técnicas diferentes. Sistemas de PBAT-amido com 10, 20 e 30% de CA foram obtidos em misturador interno e avaliados através do ensaio de biodegradação por perda de massa em solo simulado e utilizando teste de Sturm. Os ensaios por perda de massa indicam que o ataque dos micro-organismos ocorre preferencialmente na matriz. No entanto, o ambiente utilizado no teste Sturm, para avaliação da biodegradação, foi favorável a biodegradação das amostras com casca de arroz.
