Preparation of thermoplastic starch

, 1997
Native starch and WX-starch, i.e., native starch enriched with amylopectin, were mixed with plasticizers and thermomechanically treated in a twin screw mixer in order to obtain thermoplastic starch. Ethylene glycol, propane tricl (glycerine) or poly(ethylene glycol) with a molar mass less than 1000 g/mol were used as plasticizers.

ANTIBACTERIAL THERMOPLASTIC STARCH-CHITOSAN BASED MATERIALS PREPARED BY MELT-MIXING

BioResources, 2012
Antibacterial thermoplastic starch-chitosan based materials were successfully prepared by melt-mixing. The effect of chitosan modification (quaternization and grafting of long carbon chains) on the properties of the materials was also studied.

Thermo-mechanical processing of sugar beet pulp. II. Thermal and rheological properties of thermoplastic SBP [PDF]

, 2006
Thermoplastic properties of extruded sugar beet pulp (SBP) are closely linked to water–polymer relationships. DSC analyses of water evaporation, water fusion and biopolymer relaxation according to SBP moisture content gave a more accurate estimation of ...
