EFFECT OF THE CHEMICAL STRUCTURE OF CROSSLINKING AGENTS ON THE PHYSICAL PROPERTIES OF POLYMER FILMS BASED ON STARCH

Abstract

To study the effect of active functional groups of cross-linking agents on the physical properties of starch polymer films. Standardized methods for studying the indicators of physical properties of polymer films have been applied. The paper presents the results of the study of the effect of crosslinking agents of different chemical structure on the physicomechanical properties, the influence of atmospheric moisture and the resistance to wet treatments of starch polymer films. An improvement in studied parameters of the films with the use of L-tartaric acid was established. It has been proved that the use of L-tartaric acid as a crosslinking agent makes it possible to improve the physical properties of polymer films based on starch. The obtained experimental results are of practical importance for the development of new environmentally friendly polymer materials.
