Influence of oxidized starch on the properties of thermoplastic starch
Carbohydrate Polymers, 2013Thermoplastic starch was prepared by adding oxidized starches and glycerol together into starch. The addition of oxidized starch improved the rheological properties and also increased the toughness of thermoplastic starch. Compared with TPS30, the elongation at break increased from 126.8% to 152.5% when 5wt% OS 117% was added.

Film blowing of thermoplastic starch
Carbohydrate Polymers, 2008Thermoplastic starch materials are often based on a combination of starch, glycerol and water. In the present study, two potato starch grades were employed; a native (natural) grade and an oxidised and hydroxypropylated grade of the native material, in order to produce the thermoplastic material.

Thermoplastic Starch−Waxy Maize Starch Nanocrystals Nanocomposites
Biomacromolecules, 2006Waxy maize starch nanocrystals obtained by hydrolysis of native granules were used as a reinforcing agent in a thermoplastic waxy maize starch matrix plasticized with glycerol. Compared to our previous studies on starch nanocrystals reinforced natural rubber (NR) [Macromolecules 2005, 38, 3783; 2005, 38, 9161], the present system presents two ...

Macromolecular Symposia, 2000
AbstractThe thermoplastics processing of native starch in the presence of water is a recent development with very wide possible applications. Eventually, oil‐based polymer materials have to be replaced in many applications by sustainable, inexpensive, natural materials from renewable resources. The present contribution focuses on the injection moulding

Synthesis and properties of thermoplastic starch laurates
Carbohydrate Research, 2019Maize starch was allowed to react homogeneously in N,N-dimethylacetamide (DMAc)/LiCl with lauric acid activated with 4-toluenesulfonyl chloride, N,N'-dicyclohexylcarbodiimide/4-(1-pyrrolidinyl)pyridine, 1,1'-carbonyldiimidazole, and N,N-dimethylformamide (DMF) combined with oxalyl chloride.

Thermoplastic Starch Processing and Characteristics—A Review
Critical Reviews in Food Science and Nutrition, 2014Canola Council of Canada, Winnipeg, Manitoba, Canada The rising costs of nonrenewable feedstocks and environmental concerns with their industrial usage have encouraged the study and development of renewable products, including thermoplastic starch (TPS).

Biocomposites of thermoplastic starch with surfactant
Carbohydrate Polymers, 2008Abstract Thermoplastic starch films were prepared by a casting technique. Microfibrillated fibers from husks of corncobs were added as reinforcing agents and glyceryl monostearate (GMS) as surfactant. The films were characterized using X-ray diffraction studies, thermal and mechanical analysis and water uptake experiments.

Thermoreversible crosslinked thermoplastic starch
Polymer International, 2015AbstractA novel furan‐modified thermoreversible crosslinked thermoplastic starch was synthesized. The crosslinking mechanism was based on a thermoreversible furan/maleimide adduct formed by the Diels − Alder reaction. Thermoplastic starch (TPS) was first modified by forming a urethane linkage between the product of the reaction of furfuryl alcohol with

Gelatinization of Thermoplastic Starch Polymers [PDF]
This project was carried out in conjunction with Plantic Technologies, which has developed and now manufactures a new low cost, starch-based biodegradable plastic. The aim of this project was to determine the effect of varying the number of extrusion stages on the degree of gelatinization of the extrudate to be used in injection moulded, starch-based ...
