Abstract—Ternary systems of low-density polyethylene (LDPE) with polysaccharides (cellulose, starch,
chitin, and chitosan) have been prepared under shear deformation in a rotor disperser. The ternary blends exhib-
its enhanced biodegradability and rather high mechanical characteristics. SEM demonstrates that biodestruc-
tion involves not only polysaccharides but also the polyethylene matrix. This is also supported
byIRspectroscopy, which reveals that biodestruction is accompanied by an increase in crystallinity of the ini-
tial LDPE.
