Asphaltene-based composite with LDPE crystallites

Abstract

A low density polyethylene-asphaltene composition and a method of preparation of the low density polyethylene-asphaltene composition, the composition comprising an asphaltene, wherein the asphaltene is extracted from at least one of a heavy atmospheric residue, oil sands, bitumen, and biodegraded oils, and a weight percent of the asphaltene is 0.1%-25% relative to a total weight of the composition; and a low density polyethylene polymer with a density of 0.9 g/cm3-0.95 g/cm3. The asphaltene and the low density polyethylene polymer are uniformly dispersed throughout the low density polyethylene-asphaltene composition, the low density polyethylene-asphaltene composition has a weight loss onset 4° C.-20° C. higher than an average weight loss onset of the low density polyethylene polymer, and the low density polyethylene-asphaltene composition has a degree of crystallinity of 27%-34%.
