The purpose of this this thesis was the development of a quantitative test for polyethylene in paper. A review of the literature discloses that no published method exists; however valuable information was obtained, which directed the planning of the experimental work. A method was developed for the determination of polyethylene in paper. This method involves the extraction of paper in a Soxhlet extractor with CCl4. The extract is evaporated to near dryness. The residue, containing polyethylene and waxes, is than extracted with diethyl ether to remove the waxes. The results of this method show that it is accurate on high molecular weight polyethylenes; however, its accuracy declines with lower molecular weights.
