Abstract
In this work, polylactide/natural rubber composite materials obtained from a solution were studied. The addition of natural rubber to the polylactide matrix increases the elasticity of the composite material. The main factors causing breakage of the polymer chain during biodegradation under environmental conditions are mi- croorganisms, enzymes, and water. Polylactide, despite its hydrophobicity, is well exposed to hydrolytic degra- dation. It has been established that when exposed to water, the structure, and properties of polylactide and composites based on it with the addition of natural rubber change. There is an increase in the PLA melting point by 2 °C and the PLA degree of crystallinity by 4 %. Changes in the chemical structure of the samples were recorded by IR spectroscopy.
