REPORT FORM: SYNTHETIC POLYMERS Polystyrene Record your observations after the cooled solution is poured into methanol. Describe the solid you collect. Describe the fibers formed from the melted polystyrene. Nylon Describe what occurs at the interface between the two solutions. Describe the rope formed by pulling polymer out from the liquid/liquid interface.
Describe the polymer formed by vigorously stirring the remaining solutions together. Describe the fibers formed from the melted nylon polymer Questions 1. In the formation of polystyrene, hundreds of individual styrene monomers come together to form a polymer, as shown below (only a very small fragment of the polymer is shown; imagine the chain extending in each direction by hundreds of subunits): many What monomers would be used to make each of the following polymers? Cl Ci Cl Cl
139 2. The growth of a polymer involves the stepwise addition of individual monomers to the growing chain. In the first reaction below, one electron from the carbon-carbon double bond combines with the unpaired electron on the radical species to form a new single bond, but one electron is left over to form a new radical species. What will be the structure after another monomer subunit is added? 3. In the formation of a polymer, the number of individual subunits that make up the chain has an effect on the properties of the polymer formed. You made nylon polymers in two different ways, by slowly drawing out a rope and by vigorously stirring the two solutions. Which nylon polymer has longer chains?
140 4. In this lab, you specifically formed nylon 6-6, as shown below (only a very small fragment of the polymer is shown; imagine the chain extending in each direction by hundreds of subunits). Cl many What is the byproduct of this process? Nearly 5.5 million tons of nylon are formed industrially each year. If the above process were used, what potential environmental hazard must be considered?
141 There are many different nylons in addition to the nylon 6-6 you synthesized. The properties of these nylons despend on the monomers used in their formation. What monomers would be used for the synthesis of the nylons shown below (again, only a small fragment of each is shown)?
