| Organic Chemistry - Polymers | 9b | Polarized Light and Organic Molecules | Demonstration of polarized filters and polarimeter |
| When plane polarized white light is passed through a cylinder of aqueous sucrose, a spiral rainbow of color is observed | |||
| Rainbow images of plastic objects under polarized light | |||
| Polarization of liquid crystal display of a calculator | |||
| 16a | Formaldehyde Copolymers | Polymers of formaldehyde with phenol, urea, and aniline are prepared and properties compared. | |
| Commercial products of Bakelite and ureaformaldehyde resins | |||
| 16b | Synthesis of Nylon (6,6) - Nylon Rope | Nylon forms at the interface of 2 immiscible liquids and is pulled from the solution as a rope | |
| Equation | |||
| 16c | High and Low Density Polyethylene | Samples of high density polyethylene (from a milk bottle) and low density polyethylene (from a squeeze bottle) are separated by placing them in aqueous ethanol. The high density sample sinks, and the low density sample floats. | |
| 16d | Combustion of Polystyrene and Polyethylene | Samples of polyethylene (milk bottle) and polystyrene (medicine cup) are burned. Polystyrene burns with a smoky flame. Polyethylene burns with a clear flame. | |
| 16e | Beilstein Test for Poly(vinyl chloride) | Bottles of poly(ethylene terphthalate) (PET) and poly(vinyl chloride) (PVC) are touched with a hot copper wire which is then placed in the flame of a Bunsen burner. After the wire is touched to the PVC bottle a green flame is produced indicating the presence of chlorine. A colorless flame results after touching the PET bottle. |
