“…The mass loss in the range of 140–392 °C is due to the decomposition of small molecules and the breakage of unstable chemical bonds. 392–600 °C is the main stage of mass loss, which is caused by the disruption of the cross-linking network in the XMA and the breakage of C–O and CO in the polymer . In addition, the residual carbon amount was 16.46% and 14.33% for HP and HPA, respectively, while the residual carbon amount reached 21.29% for XMA.…”

Preparing a biobased wood adhesive to solve the formaldehyde pollution problem is crucial. In this study, a xylitolmaleic anhydride hyperbranched polyester resin (XMA) was prepared from two biomass raw materials, xylitol (X) and maleic anhydride (MA). Hyperbranched polyol (HP) and hyperbranched polyacid (HPA) were synthesized via a nucleophilic addition reaction by regulating the molar ratio of X to MA. Then XMA was prepared by melt polycondensation of HP with HPA. The chemical structure of XMA was characterized using Fourier transform infrared spectroscopy (FTIR), 13 C nuclear magnetic resonance ( 13 C NMR), liquid chromatography−mass spectrometry (LC-MS), and gel permeation chromatography (GPC). This double hyperbranched synthesis strategy increases the internal cross-link density of the resin and imparts excellent mechanical properties. Mechanical tests showed that the dry shear strength of the plywood reached 2.37 MPa, and the strengths were 1.72 and 1.75 MPa after immersion in hot and boiling water for 3 h. The green and simple synthesis strategy of XMA is expected to be applied in the wood industry.

“…A peak attributed to C = O was generated at 1706 cm − 1 , proving that MA reacted with chitosan and produced amide or ester groups. Secondly, compared to CSC, the absorption peak in CSC-G shifted from 1706 cm − 1 to 1714 cm − 1 , and the peak width was signi cantly enhanced, indicating that the carboxyl groups in CSC reacted with the hydroxyl groups on glucose to generate more esters [33], forming a cross-linked structure. In addition, a new broad peak appeared at 3600 cm − 1 , which belongs to the hydroxyl group on glucose [34], indicating that the adhesive contains many hydrogen bonds, which is also why CSC-G has good bonding performance.…”

“…Our group reported that star-shaped poly(trimethylpropane-succinate-ethylene glycol esters) prepared by a multistep reaction was superior to glycerol in improving starch toughness, inhibiting the recrystallization of starch, and increasing the resistance towards humidity [18]. Non-linear polymers, especially hyperbranched polymer, have attracted considerable attention owing to their simple preparation process, low cost, and excellent chemical properties [19][20][21][22]. Our group found that poly(glycerol citrates) synthesized by a one-step reaction was also superior to glycerol in plasticizing starch, and resisting the aging of thermoplastic starch [23].…”

Thermoplastic starch plasticized with glycerol is very sensitive to humidity and aging. In this study, hyperbranched poly(1,4-butanediol citrate) is prepared via a one-step method, and is mixed with glycerol as the co-plasticizer of starch to prepare thermoplastic starch films. The structure of hyperbranched poly(1,4-butanediol citrate) is studied by performing Fourier-transform infrared spectroscopy and 1H nuclear magnetic resonance analyses. The interaction between starch and co-plasticizer, and crystallinity, mechanical properties, anti-aging properties, thermal stability, transmittance, and moisture absorption of thermoplastic starch films are studied. The results illustrate that poly(1,4-butanediol citrate)/glycerol has a synergistic effect on the plasticization, anti-aging properties, transmittance, and moisture adsorption properties of thermoplastic starch films. The thermoplastic starch film with a poly(1,4-butanediol citrate)/glycerol weight ratio of 2:28 has the maximum elongation at break, the highest transmittance, the optimal ability to inhibit the long-term retrogradation of starch and the lowest moisture content at the relative humidity of 68%. Elongation at break of thermoplastic starch film with poly(1, 4-butanediol citrate)/glycerol at 2/28 and stored for 3 and 30 days are (101.1 ± 14.0)% and (91.7 ± 2.7)%, respectively, which are 1.8 and 4.4 times that of the thermoplastic starch film with only glycerol, respectively. These phenomenon not only depend on the interaction between starch and co-plasticizer, but also may be related to the compatibility between starch and co-plasticizer. Thus, the poly(1,4-butanediol citrate)/glycerol combination has potential applications in the processing of thermoplastic starch. 1 Introduction
