“…Additionally this is a method for reducing the raw material costs due to the low price of unmodified starch. One of the first applications of starch in the plastic industry was its use in the production of polyurethane foams [1, 2]. In addition, starch was used in poly(viny1 chloride) films [3] and in cast films with poly(viny1 alcohol), glycerol, surfactant, and formaldehyde [4].…”

Foams produced from blends of an ethylene‐vinyl acetate copolymer (EVA) with high VA (vinyl acetate) content (28%) and corn starch have been successfully fabricated using an improved compression molding technique. A detailed characterization of the structure and physical properties has been carried out. The results showed that the corn starch acts as filler for EVA, showing a good compatibility with the polyolefin. Different types of cellular structure (closed, partially interconnected, and fully interconnected) and cell sizes were obtained depending on the relative density and the amount of starch included in the composition. Besides, the addition of starch allows tailoring the physical properties of the composite foams. An increase in the starch content leads to an increase of the density, compressive strength, hardness, and thermal conductivity and a decrease of the elasticity. Finally, biodegradability tests showed how increases the biodegradation with the amount of starch in the foam, which reaches 60% at 100 days for the foam with 70% of starch. POLYM. ENG.

“…In general, fillers and extenders are incorporated into the plastic materials to either introduce particular characteristics, to improve their physicochemical properties, or to reduce the cost of the product. In the past four decades, many researchers4–11 have been interested in the use of renewable resources in the plastics industry. Polysaccharides were incorporated into polyurethane systems successfully.…”

Linear low-density polyethylene (LLDPE) cast films were prepared with native and modified (octenyl succinate) corn starch, and their properties were investigated. The optimum conditions for continuous compounding were 205 "C and 20 rpm. Physical properties of LLDPE containing starch octenyl succinate (SOS) were compared to the cast films that contained native corn starch (NCS). The addition of either starch to LLDPE decreased the tensile strength and elongation and increased the water absorption. In all cases, SOS/LLDPE cast films showed higher tensile strength and elongation values than did corresponding NCS/LLDPE cast films. The biodegradation rate of starch for SOS-containing films was lower than the rate observed for NCS-containing films.
