Do PTSes improve the aging stability of starch film?
In the sense of breaking elongation, PTSEs could not improve the aging stability of starch film, but promote the aging of starch film. The star polyesters with longer branched chains did not play a role in reducing the elongation of the starch film. 3.5. Moisture absorption
What is a star polyester?
For these special properties, star polyesters are commonly used in many fields, such as drug delivery, coatings and starch plasticizing [ , , ]. Compared to hyperbranched polyesters, a star polyester with a simpler structure consisted of a core and multiple arms, is easy to prepare and to obtain its tailed structure.
How do PTSes improve elongation of starch film?
The addition of star polyester PTSEs increased the elongation at break of the starch film, thus improving the mechanical properties of the starch. The longer the PTSE branch chain was, the better the plasticizing effect.
Does PTSE affect starch structure & properties of starch paste & film?
Longer chain of star polyester benefits some properties of the starch paste and film. H nuclear magnetic resonance and gel permeation chromatography, and the effects of PTSEs on the structure and properties of starch were studied by X-ray diffraction, rapid viscosity analysis, moisture absorption test, mechanical and thermal analysis.
What is a stepwise-synthesized star polyester?
The stepwise-synthesized star polyesters with the Mn of 478, 820, 1249, 1611 and 1941, respectively. With the increase of monomerst of diacid SA and diol EG, the chain of the star polyester increased but not evenly, characterized by FTIR and 1 H NMR.
How do H-bonds affect the thermal stability of starch films?
The changes of H-bonds also brought about the weight loss in thermal degradation of starch films and decreased the thermal stability. The addition of star polyester PTSEs increased the elongation at break of the starch film, thus improving the mechanical properties of the starch.
