Thermal Analysis/Deformation
This is equal to the load (force) applied over an area
What is stress?
The transfer of substances originally present in the plastic material into the packaged product.
What is migration?
This is the polymer for formed from this monomer: C2H4
What is polyethylene?
If you melt PET with any of this present, it will degrade and lose molecular weight.
What is water?
In Georgia, it is illegal to eat this with a fork.
What is fried chicken?
The area of a stress strain curve in which there is an increase in elongation with little to no increase in stress.
What is cold drawing?
This test holds a polymer at a fixed load and measures the amount of resulting stress over time or with increased temperature.
What is stress relaxation?
The most common initiator used in addition chain growth polymerization is this.
What is free radical?
This is the family of condensation polymers that are formed from the combination of an amino group + carboxyl group.
What are polyamides?
Of the six main characters on the TV show “Friends,” this character never got married.
Who is Joey?
This thermal analysis test shows the change in length of a material as temperature is increased.
What is TMA (ThermoMechanical Analysis)?
These are the 4 regions of a time temperature superposition.
What are glassy, leathery, rubbery plateau, and viscous flow?
This type of catalyst is used to create linear polyethylene (HDPE).
What is Zieglar Natta?
This is how we determine the numeric part of the naming convention for Nylon.
What is the number of Carbons in the monomers?

Who is Alec Baldwin?
This region of a stress strain cure is when we will no longer view elastic deformation for even a portion of the material.
What is strain hardening?
The area underneath a stress strain curve up until the yield point is known as this value.
What is resilience?
This catalyst breaks the rules that govern traditional polyethylenes and allows for unique performance characteristics.
What is metallocenes?
This polyamide is formed using a ring-opening technique and was created to get around the Dow patent for a similar product.
What is Nylon 6?
This is the national animal of Scotland.
What is the unicorn?
This type of thermal analysis can be used to study degradation properties of polymers.
When measuring the increase in weight of a salty snack package over a period of time, when there is a period of time when there is no longer any increase in weight we know that this has occured for the package, snack and the atmosphere.
What is equilibrium?
This polymer is formed from this repeating unit: C2H2Cl2
What is polyvinylidene chloride?
This condensation polymer is formed by the combination of terephthalic acid and ethylene glycol.
What is polyethylene terephthalate?
This is the number of states the Appalachian Trail crosses.
What is 14 states?
