Biotechnologically 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 solution at mild temperature mediated by polymer-supported Candida antarctica lipase B (CALB). Two series of random copolyesters (PBxGluxySeb and PBSebxGluxy) were prepared differing in which d-glucose derivative (Glux diol or Glux diester) was used as comonomer. The three parent homopolyesters ...

Two 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 respectively, in the preparation of PET-based copolyesters by polycondensation in the melt. Synthesis results, structure and thermal properties of the two afforded copolyester series were evaluated and compared regarding composition and type of comonomer used in each case. ...

A cyclic acetal of dimethyl l-tartrate (dimethyl 2,3-di-O-methylene l-threarate, Thx) was used as comonomer of dimethyl terephthalate (DMT) in the polycondensation with 1,6-hexanediol (HD) in the melt. Random copolyesters PHTxThxy with contents in tartrate units up to 50% were obtained with satisfactory molecular weights (Mw between 20,000 and 50,000) and dispersities slightly above 2, and without apparent discoloration. The copolyesters started to decompose above 300 °C. The Tg of the copolyesters oscillated ...

Two series of bio-based PBT copolyesters were obtained by polycondensation in the melt of 2,4:3,5-di-O-methylene-D-glucitol (Glux-diol) or dimethyl 2,4:3,5-di-O-methylene-D-glucarate (Glux-diester) with 1,4-butanediol and dimethyl terephthalate. The glucose-based bicyclic compounds used as comonomers were synthesized from commercially available 1,5-D-gluconolactone. The prepared PBT copolyesters had weight-average molecular weights in the 30 000–50 000 range; they had a random microstructure, and ...

2,4:3,5-Di-O-methylene-D-glucitol (Glux-diol) and dimethyl 2,4:3,5-di-O-methylene-D-glucarate (Glux-diester) have been copolymerized with ethylene glycol and dimethyl terephthalate by polycondensation in the bulk to produce PET copolyesters as well as their respective homopolyesters. These sugar-based bicyclic monomers were synthesized from 1,5-D-gluconolactone, a commercially accessible compound derived from D-glucose. The PET copolyesters with either the diol or the diacid counterpart partially ...

The diacetalized diol 2,4:3,5-di-O-methylene-D-glucitol (Glux), a bicyclic compound derived from D-glucose, was used as a comonomer of 1,6-hexanediol in polycondensation in the melt with dimethyl terephthalate to produce a set of aromatic copolyesters (PHxGluxyT) with Glux contents ranging from 5 to 32%-mole. These sustainable copolyesters had molecular weights within the 12,000 to 45,000 g mol−1 range, and polydispersities between 2.0 and 2.5. They all had a random microstructure and displayed slight ...

Este artigo aborda a conexão entre perspectivismo e gênero a partir da etnografia airo-pai da linguagem xamânica dos seres celestes, bem como as relações interespecíficas que a atravessam. Examino as conexões entre perspectivismo, totemismo e gênero presentes nos cantos da puberdade masculina e na exegese indígena desses cantos. Argumentoque o gênero surge de múltiplas relações interespecíficas e se expressa cotidiana e ritualmente, especialmente nos ensinos xamânicos da puberdade masculina, que ...

A set of copolyesters (PHT x Glux y ) with compositions ranging between 90/10 and 50/50 in addition to the parent homopolyesters poly(hexamethylene terephthalate) (PHT) and PHGlux, are prepared by the melt polycondensation of 1,6‐hexanediol (HD) with mixtures of dimethyl terephthalate (DMT) and dimethyl 2,4:3,5‐di‐ O ‐methylene‐ d ‐glucarate (Glux). The copolyesters have in the 35 000–45 000 g mol −1 range, their microstructure is random, and they start to decompose at a temperature well above 300 °C. Crystallinity ...

This study was carried out to investigate the nutritional composition and functional properties of two varieties of watermelon seeds and compare these properties between these seeds for harnessing them for consumption as food. The dried seeds of the two types of watermelon were evaluated by using a standard method for different characteristics such as nutritional, phytochemical and functional properties to perceive the potential benefits of that seed. The result of nutritional composition and phytochemical ...
