Abstract
This lab experiment illustrates the use of differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA) in the measurement of polymer properties. A total of seven exercises are described. These are dry exercises: students interpret previously recorded scans. They do not perform the experiments. DSC was used to determine the percent crystallinity of a polypropylene (PP) dog bone before and after it was pulled on an Instron machine. Using DSC, the percent crystallinity of a polyethylene terephthalate (PET) preform was determined and compared with a PET pop bottle. DSC was also used to explore the effect of molecular weight on the glass transition temperature of a series of polystyrene standards. Using a combination of DSC and IR spectroscopy the plastics in automobile headlights and taillights were identified. The same two techniques were also used to examine two commercial nylon samples: fishing line and a tea bag. TGA was used to examine the filler-reinforcement content in a series of PP...
