Condensation Polymerization: Preparation of Two Types of Polyesters
College-level or AP chemists use phthalic anhydride to synthesize two different polyesters, one linear and one cross-linked in structure. A detailed materials list and well-written procedures are provided on a lab sheet. Learners write...

Investigating the Effect Of Successive Heat and Cool Cycles on a Thermoplastic material.
Students investigate hot melt glue using a hot melt glue gun as an an injection molding simulator and a melt index viscometer. They evaluate the effect of heating and cooling by weighing the glue extruded over a constant time period.

Addition Polymerization: Preparation of Polystyrene Using Two Types of Initiators
Advanced chemistry classes compare the polymerization of styrene using two different initators: benzoyl peroxide and aluminum chloride. Once they synthesize polystyrene, they compare the two producet for melting point and density. There...

Condensation Polymerization: Preparation of Nylon 6/6
Students participate in a lab activity in which they synthesize nylon 6/6, calculate the percent yield by mass, identify the polymer as thermoplastic or thermoset, and determine the melting point, density and end-product use of the polymer.

Properties and Perfectly Polymeric Sodas
Pupils examine physical and chemical properties of plastics, interfaces of plastics, and forms of plastics. In three lab activities, students discover the two characteristic responses of plastics to heating, thermoplastic or thermosetting.

Serc: Mn Step: Shrinky Dink Chemistry
In this lesson, students first learn about thermoplastics, and about polystyrene in particular, which is a #6 plastic. They will then heat different #6 plastics to create shrinky dinks. As they are heated, they shrink, which is a...
