EFFECT OF SEBS CONTENT ON MORPHOLOGICAL AND MECHANICAL PROPERTIES OF LDPE/SEBS BLEND COMPATIBILIZED WITH PE-g-MA

Abstract

This work discusses the preparation and analysis of films made from a blend of LDPE (low-density polyethylene) and SEBS (styrene-ethylene-butylene-styrene) that is compatible with PE-g-MA (polyethylene-graft-maleic anhydride). The study explores the influence of SEBS content on the film formation capacity and morphological and mechanical properties of the blend. The results indicate that the film formation capacity is affected by the strain-softening property of SEBS. A blend with 10% SEBS demonstrated better film formation compared to the one containing 30% SEBS. Despite the challenges in blown film production due to the strain-softening property of SEBS, the blend has potential for other applications.
