Structure and properties of compositions of linear low-density polyethylene with starch

Grafted copolymers of low-molecular-weight polyethylene with acrylic acid were used as compatibilizers in polymer compositions based on linear low-density polyethylene and starch. Using atomic force microscopy, X-ray diffraction analysis, and physical and mechanical tests, it was determined that the presence of a graft copolymer in the composition improves the distribution of starch particles in the polyethylene matrix, affecting the supramolecular structure and the physical and mechanical properties of the composition.
