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...

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
This organic chemistry lab activity is appropriate for teaching polymerization, percent yield, melting point, or the types and uses of polymer materials. Chemistry pupils imagine that they are working for a company to develop a special...

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.

Thermoset Polymers
Students complete a lab activity with polymers to allow them to better understand how to make "observations". In this science lesson students make measurements and collect data.

Teach Engineering: Bridging to Polymers: Thermoset Lab
Students act as engineers to learn about the strengths of various epoxy-amine mixtures, and observe the unique characteristics of different mixtures of epoxies and hardeners. Student groups make and optimize thermosets by combining two...

Teach Engineering: Close Encounters of the Polymer Kind
Students explore the basic characteristics of polymers through the introduction of two polymer categories: thermoplastics and thermosets.
