The Influence of Initiator Concentration on the Molecular Weight of Polystyrene

This in-depth organic chemistry lab walks learners through an investigation of the effect of initiator concentration on the resulting molecular weight of polystyrene. It is important that you use this lesson with experienced chemistry learners as they will synthesize polystyrene several times and calculate efflux time and viscosity. Ideally you would use this when teaching your class about polymerization.
