The biodegradation process of composites based on low-density polyethylene (LDPE) and thermoplastic starch (TPS) of different origin, such as corn, pea, and rice, was studied. Thermoplastic starch was derived from native starches of different types by their processing in Brabender and MachPlast laboratory extruders (Russia). A positive effect (biodegradation acceleration) from the use of new types of starch plasticizers, namely, monoglycerides distilled in TPS/polyethylene composites was confirmed. Intensive sporulation of active microorganisms was observed on the surface of samples in 6 months. At the same time, the water absorption of samples attained 30% with a 60% decrease in their strength and deformation properties to indicate an intensive character of biodegradation. The biodegradation rate was established to depend on the distribution of a natural biodegradable filler in a composition with a synthetic polymer. [ABSTRACT FROM AUTHOR] |
