1. Polymer Recycling Pick 2 common plastics (from those which correspond to 1-6 recycling codes) and discuss the process or methods used in recycling that polymer. Discuss the recycling processes most commonly applied to that polymer. Include general energy requirements and list other needed chemicals and equipment, as well as the resing products from separation/degradation. Give 3 examples of materials which can be made from these "down-cycled" plastics. Give two challenges of each recycling process, respectively.
What is the air quality in your community? What type of pollution is affecting your community? Using the water calculator, how much water do you use per day? Discuss the impact of your water usage and ways to lessen the amount of water your household uses per day. If you pay for water, take a look at your water bill. Is it higher or lower than you expect? Does your community participate in a mandatory recycling program? Are there recycling...
MAKE-UP Question 2 PETE is the shorthand name for a polymer that is commonly used to create plastic bottles for soda beverages. Examples of these bottles and the recycling symbol for PETE are shown in the photograph The two monomer units that are used to make PETE are given below (a) Draw a diagram to illustrate how these two monomers are joined by a condensation reaction (include the molecular structures of all the reactants and the products) type of chemical...

(B)A stress of 6.7 MPa is employed to one type of a polymer under constant strain. After 40 days at 20 °C the stress is reduced to only 8.4 MPa. When the same polymer is heated to 40 °C the relaxation time is 40 days. 1- Calculate the relaxation time constant for this material at 25 °C? 2- Estimate the stress after 50 days at 25 °C? 3- Estimate the stress relaxation activation energy for the same polymer.
