Abstract
An undergraduate laboratory experiment has been developed in which the students extract and analyze the additives from plastic food wrap, Tygon tubing and plastic soda bottles that have been crushed in a bottle return machine. The modifiers are extracted from the plastics using methylene chloride and/or methanol as solvents and the extracts are analyzed by GC/MS. Identifications are carried out by a combination of automated computer and manual library searches and chromatographic retention indices.
