Evaluation of Biodegradability of Poly(Butylene succinate-co-butylene Adipate) on the Basis of Copolymer Composition Determined by Thermally Assisted Hydrolysis and Methylation-Gas Chromatography

Rapid and Direct Compositional Analysis of Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) in Whole Bacterial Cells by Thermally Assisted Hydrolysis and Methylation-Gas Chromatography

“…0.02 mg) of the film samples. 15,16 In this work, the biodegradation behavior of PBSA was also evaluated by focusing on the change in copolymer compositions measured by THM-GC. Furthermore, we have also exploited this technique to determine the copolymer composition of trace amounts (ca.…”

“…[13][14][15][16] The THM reaction under optimized conditions allows for the quantitative detection of the constituent monomers in the polymer chains as their corresponding methyl derivatives through selective hydrolysis of the ester or carbonate linkages and subsequent methylation by TMAH. The authors reported that the copolymer composition of a biodegradable copolyester, poly(butylene succinate-co-butylene adipate) (PBSA), was successfully determined by means of THM-GC using trace amounts (ca.…”

Direct determination of poly(3-hydroxybutyrate) accumulated in bacteria by thermally assisted hydrolysis and methylation-gas chromatography in the presence of organic alkali

“…The THM-GC system in this study was basically the same as that described in our previous papers [10][11][12][13]. A vertical microfurnance pyrolyzer (Frontier Laboratories, PY-2010D) was attached to a GC (Agilent, HP 4890) equipped with a flame ionization detector (FID).…”

“…Recently, a thermally assisted hydrolysis and methylation-gas chromatography (THM-GC) method in the presence of strong organic alkali such as tetramethylammonium hydroxide (TMAH) has become a useful technique for structural and compositional analyses of various condensation polymers [3,[9][10][11][12][13]. This method often provides extremely simplified and quantitative chromatograms mainly consisting of methyl derivatives of the constituent monomers in the polymer chains.…”

“…Si bien los grados médicos de estos poliésteres son extremadamente caros, las diferentes empresas fabricantes, ofrecen actualmente un amplio rango de grados comerciales que permiten el empleo de estos, en aplicaciones industriales en forma de barras, films, fibras, tejidos, etc. [19][20][21][22][23] Merece la pena destacar que diversos poliésteres alifáticos como la -policaprolactona, PCL, el poli(butilén succinato), PBS [24][25][26] o algunos copoliésteres que incorporan componentes tanto alifáticos como aromáticos, como el poli(butilén succinato-co-adipato)-PBSA [27,28] o el poli(butilén adipato-co-tereftalato)-PBAT [29,30] , etc. entre otros, están empezando a utilizarse de forma creciente en el sector envase-embalaje reduciendo, en gran medida la problemática ligada a la generación de residuos en dicho sector.…”
