Effect of compounding and starch modification on properties of starch-filled low-density polyethylene Academic Article uri icon

abstract

  • Linear low-density polyethylene (LLDPE) cast films were prepared with native and modified (octenyl succinate) com 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. © 1991, American Chemical Society. All rights reserved.
