Aliphatic polyester-grafted starch-like polysaccharides by ring-opening polymerization

Structure, properties and interfacial interactions in poly(lactic acid)/polyurethane blends prepared by reactive processing

“…However, one-step blending and compatibilization possesses several advantages, both from an economical and environmental point of view, since it enables the elimination of several processing steps. Such a process was reported by Dubois et al [47,48] more than ten years ago. The ring-opening polymerization (ROP) of cyclic esters initiated by the hydroxyl groups of biopolymers like starch [47], dextran [48] or partially substituted cellulose acetate [49][50][51] is a convenient method for the preparation of block copolymers via reactive processing, although various other combinations are also possible.…”

Starch-based completely biodegradable polymer materials

“…It is linear, hydrophobic, partially crystalline polyester, and can be slowly degraded by microbes [27][28][29]. Blends between starch and PCL have been well documented in the literatures [30][31][32][33][34][35]. The weakness of pure starch materials including low resilience, high moisture sensitivity and high shrinkage has been overcome by adding PCL to starch matrix even at low PCL concentration.…”

Physical properties and biodegradability of maleated-polycaprolactone/starch composite

“…Studies by Bikiaris and Panayiotou [14] showed that maleic anhydridegrafted-polyethylene (PE-g-MAH) increased the compatibility between low-density polyethylene (LDPE) and plasticized starch. This suggests that the blending of PCL with the cheaper material starch, with a reactive functional group grafted onto PCL to improve adhesion and dispersion of the two immiscible phases, offers the best combination of cheapness and good mechanical properties [15,16].…”
