摘要：

In the present study the effect that the ethylene-acrylic acid copolymer (EAA) and plasticized starch (PLST) have upon the thermooxidative degradation of low density polyethylene (LDPE) was examined. The course of oxidation was followed using a carbonyl index derived from FTIR measurements and thermogravimetric measurements of weight changes observed in incubated samples. Three types of blends were examined: LDPE/starch, LDPE/EAA, and LDPE/starch/EAA. The measurements indicate that EAA accelerates LDPE thermooxidation whereas PLST inhibits it. The influence of the thermooxidative process on the tensile strength and the elongation at the break of the blends was also examined. (C) 1997 Elsevier Science Limited.
