Bio-based PBS copolyesters derived from a bicyclic D-glucitol
(2015-05-12)
Article
Accés obert2,4:3,5-di-O-methylene-D-glucitol (Glux-diol) was used for the synthesis of poly(butylene succinate) (PBS) copolyesters by melt polycondensation. Glux-diol possess a rigid bicyclic asymmetric structure made of two fused ... -
Bio-based poly(ethylene terephthalate) copolyesters made from cyclic monomers derived from tartaric acid
(Elsevier, 2014-05-13)
Article
Accés restringit per política de l'editorialTwo cyclic acetal compounds, 2,3-O-methylene L-threitol and dimethyl 2,3-O-methylene L-threarate, both coming from naturally-occurring tartaric acid, were used as comonomers to replace ethylene glycol and dimethyl terephthalate ... -
Carbohydrate-based PBT copolyesters from a cyclic diol derived from naturally occurring tartaric acid: a comparative study regarding melt polycondensation and solid-state modification
(2014-04-01)
Article
Accés restringit per política de l'editorial2,3-O-Methylene-L-threitol (Thx) is a cyclic carbohydrate-based diol prepared by acetalization and subsequent reduction of the naturally occurring tartaric acid. The structure of Thx consists of a 1,3-dioxolane ring with ... -
Chemical structure and microstructure of poly(alkylene terephthalate)s, their copolyesters, and their blends as studied by NMR
(2014-11-17)
Article
Accés restringit per política de l'editorialThe use of NMR spectroscopy in solution to investigate the chemical structure of engineering poly(alkylene terephthalate)s such as poly(ethylene terephthalate) (PET), poly(trimethylene terephthalate) (PTT), and poly(butylene ... -
Copolyesters made from 1,4-butanediol, sebacic acid, and D-glucose by melt and enzymatic polycondensation
(2015-03-09)
Article
Accés obertBiotechnologically accessible 1,4-butanediol and vegetal oil-based diethyl sebacate were copolymerized with bicyclic acetalized d-glucose derivatives (Glux) by polycondensation both in the melt at high temperature and in ... -
Effect of hydroxyapatite nanoparticles on the degradability of random poly(butylene terephthalate-co-aliphatic dicarboxylate)s having a high content of terephthalic units
(2016-07-06)
Article
Accés obertCopolyesters derived from 1,4-butanediol and constituted also of aliphatic and aromatic dicarboxylate units in a molar ratio of 3:7 were synthesized by a two-step polycondensation procedure. Succinic, adipic, and sebacic ... -
Fully bio-based aromatic–aliphatic copolyesters: poly(butylene furandicarboxylate-co-succinate)s obtained by ring opening polymerization
(2017-01-28)
Article
Accés obertPoly(butylene 2,5-furandicarboxylate-co-succinate) copolyesters (coPBFxSy) have been synthesized by ring opening polymerization (ROP). Cyclic butylene 2,5-furandicarboxylate and butylene succinate oligomer mixtures, to ... -
Isomannide-containing poly(butylene 2,5-furandicarboxylate) copolyesters via ring opening polymerization
(American Chemical Society (ACS), 2018-05-08)
Article
Accés obertCyclic oligomers of isomannide 2,5-furandicarboxylate were synthesized using the high dilution condensation method. A mixture of dimer, trimer, and tetramer species largely enriched in dimer was obtained. These cyclic ... -
