Both polyethylene (PE) and polyethylene terephtalate (PET) are used for plastic water bottles. The monomers used to produce these plastics are: ethylene for PE phtalic acid and ethylene glycol for PET. HH н-о-с -C-0-H H-O-(CH2)2-OH IL C=C 6 Ethylene glycol Phtalic acid HH ethylene 1. For each polymer, write the chemical formula and indicate the type of polymerization reaction. 2. Are these polymers thermoplasics or thermosets? Explain. 3. What are three main reasons for the selection of PE and PET to be used as bottles for drinking water? 4. Name and explain, using your own words, the process for making PE and PET bottles. 5. Some properties of these plastics are listed in the table. Describe the differences between the two polymers in terms of chain structure and bonding.
