Combinations of low density polyethylene and starch, compatible with maleic anhydride (MA) and the sodium salt of polyethylene-co-methacrylic acid (EMA-Na), were made. By analysing mechanical characteristics, melt flow measurements, spectroscopy, thermal analysis, and scanning electron microscopy, the compatibility behaviour of blends was investigated. mixes without compatibilizer exhibit the undesirable characteristics of polymer mixes that are incompatible. The ionomer is an effective compatibilizer for low density polyethylene-starch blends, according to both spectroscopic and morphological characteristics. Based on biodegradability testing, the blends show some degree of biodegradability.
