Microstructure of Filled Biocomposites Based on Polyolefin Blends

Abstract

Binary and ternary composites based on low-density polyethylene and a copolymer of ethylene and vinyl acetate with / without the addition of microcrystalline cellulose have been investigated. The analysis of microstructure of the filled composites has shown more uniform distribution of particles at the mechanochemical treatment of the composite melt. Based on DSC study results, polymers amorphisation in the composites occurred under ultrasonic action. The stress-related characteristics of the materials increased that is explained by improved compatibility and partial copolymerization of the blended polymers.
