Acrylic nails are made by combining polymer particulates with a monomeric solution that reacts in a chain-growth polymerization reaction. When initiated, the monomers link together in a network that surrounds the polymer particles. The ratio of monomer to existing polymer particles will affect the properties of the final material. The poly- mer particulate component of acrylic nails is poly(methyl methacrylate). One of sev- eral different chemicals is used in the current nail industry as the monomer solution: isobutyl methacrylate, hydroxyethyl methacrylate, or ethyl methacrylate. (a) Draw the polymer chain that results for each of these monomers. (b) Azoisobutyronitrile (AIBN) is added into the reaction and is activated by ap- plied heat. Draw a mechanism for the reaction of hydroxyethyl methacrylate using AIBN. Show the steps of initiation, two propagation steps, and a ter- mination step where two radical polymeric chains combine. What role does AIRN serve?

The plastic known as PETE (polyethyleneterephthalate) is used to make plastic soft drink bottles and containers for salad dressing, shampoos, and dishwashing liquids. PETE is a polymer of terephthalic acid and ethylene glycol. Today, PETE is the most widely recycled of all the plastics. After it is separated from other plastics, PETE can be used in polyester fabric, door mats, and tennis ball containers. In 2015, 1.84×109 lb1.84×109 lb of PETE bottles were recycled in the U.S. The density of PETE is 1.38 g/mLg/mL. How many kilograms of PETE bottles were recycled in 2015 in the U.S.? Express your answer to three significant figures.
Teflon can be made from tetrafluoroethylene by means of a free radical polymerization. In the reaction, termination occurs only by combination and not by disproportionation. Explain this observation.
